    Implement :main (see ticket #662)
    
    Patch from Volker Stolz, minor mods by me
    
    When matching commands, we now look for (a) an exact match, and (b)
    the first prefix match we find in the list.  This is so that :module
    can still be abbreviated by :m, to avoid surprise.
    
    Docs still to do.

    Improve the GC behaviour of IORefs (see Ticket #650).
    
    This is a small change to the way IORefs interact with the GC, which
    should improve GC performance for programs with plenty of IORefs.
    
    Previously we had a single closure type for mutable variables,
    MUT_VAR.  Mutable variables were *always* on the mutable list in older
    generations, and always traversed on every GC.
    
    Now, we have two closure types: MUT_VAR_CLEAN and MUT_VAR_DIRTY.  The
    latter is on the mutable list, but the former is not.  (NB. this
    differs from MUT_ARR_PTRS_CLEAN and MUT_ARR_PTRS_DIRTY, both of which
    are on the mutable list).  writeMutVar# now implements a write
    barrier, by calling dirty_MUT_VAR() in the runtime, that does the
    necessary modification of MUT_VAR_CLEAN into MUT_VAR_DIRY, and adding
    to the mutable list if necessary.
    
    This results in some pretty dramatic speedups for GHC itself.  I've
    just measureed a 30% overall speedup compiling a 31-module program
    (anna) with the default heap settings :-D

    Improve the GC behaviour of IOArrays/STArrays
    
    See Ticket #650
    
    This is a small change to the way mutable arrays interact with the GC,
    that can have a dramatic effect on performance, and make tricks with
    unsafeThaw/unsafeFreeze redundant.  Data.HashTable should be faster
    now (I haven't measured it yet).
    
    We now have two mutable array closure types, MUT_ARR_PTRS_CLEAN and
    MUT_ARR_PTRS_DIRTY.  Both are on the mutable list if the array is in
    an old generation.  writeArray# sets the type to MUT_ARR_PTRS_DIRTY.
    The garbage collector can set the type to MUT_ARR_PTRS_CLEAN if it
    finds that no element of the array points into a younger generation
    (discovering this required a small addition to evacuate(), but rough
    tests indicate that it doesn't measurably affect performance).
    
    NOTE: none of this affects unboxed arrays (IOUArray/STUArray), only
    boxed arrays (IOArray/STArray).
    
    We could go further and extend the DIRTY bit to be per-block rather
    than for the whole array, but for now this is an easy improvement.

  3. improvements to darcs-all

    Simon Marlow authored
    - get from the same repo as the main GHC repo, if that was a local filesystem
    - allow darcs whatsnew
    - use --repodir if possible
  4. Add infrastructure for multiple library packages

    Simon Marlow authored
    The ./darcs-all script at the top level is an easier way to do darcs
    pull/push/get on the whole tree (it should probably allow more
    commands; I'll fix that later).
    
    libraries/default-packages is a list of darcs repositories with which
    to populate the libraries tree.
  5. Add a skeleton libraries directory

    Simon Marlow authored
    Adding files from libraries that aren't in the other
    packages sub-repos.  I haven't bothered to try to keep
    history for these files, for history go back to the CVS
    repo.

    GHC.runStmt: run the statement in a new thread to insulate the
    environment from bad things that the user code might do, such as fork
    a thread to send an exception back at a later time.  In order to do
    this, we had to keep track of which thread the ^C exception should go
    to in a global variable.
    
    Also, bullet-proof the top-level exception handler in GHCi a bit;
    there was a small window where an exception could get through, so if
    you lean on ^C for a while then press enter you could cause GHCi to
    exit.
