    	Alpha build fix
    	... write a slightly more general PREPARE-ARGUMENT function for
    		modular arithmetic;
    	... as discussed on #lisp IRC 2003-09-24, post-0.8.4 we can optimize
    		common cases on platforms where register width and
    		bignum-element-width are the same.

    	Treatment of --load
    	... half fix the problems.  Put LOAD into a multiple escape, so
    		that changes to the readtable don't break the
    		command-line option;
    	... log behaviour in the presence of #\" and #\* as a bug.

    	After vast effort (mostly Christophe's) we have a fix for the
    	hangs in multithreaded CLX.  Under some circumstances we could
    	be trying to scavenge one thread's stack using the stack
    	pointer from another: needless to say, this is not too effective.
    	When sleeping on a queue, loop around sigwaitinfo restarting
    	it until it stops returning EINTR

        Compilation is now successful on this platform, but two test cases
        currently fail.

    	GC fix fixes
    	Rearrange the sigcontext GCing a bit and add commentary
    	describing what's going on
    	Delete debugging message accidentally committed in .76
    	tests/threads.impure.lisp now works (but don't worry, I
    	have another test locally which still kills sbcl sometimes)

         GC fixes and miscellaneous commentary:
         Frob VOP attributes for {push-words-on,pop-words-from}-c-stack,
         per APD comment
         Comment: why WITH-PINNED-OBJECTS doesn't need an UNWIND-PROTECT
         In x86 pseudo-atomic start, clear interrupted bit _before_
         setting atomic bit, to eliminate window where a pa section might
         be interrupted immediately after starting then have the evidence
         of interruption erased
         When scavenging thread control stacks on gencgc, also look at live
         interrupt contexts that might not be on the current stack (e.g.
         alternate signal stacks).
         When stopping a thread so it may be GCed, save the signal context
         _before_ decrementing countdown_to_gc
         In lose(), send SIGSTOP to all threads other than the currently
         losing one, so we have a chance to examine what went wrong before
         they stomp all over memory

    	Implement slightly less stupid 32bit-logical-foo on the alpha
    	... including fixing the ORNOT/LOGNOR bug, natch.
    	... also, we implement a hack: converting (logand ... #xffffffff)
    		to a one-instruction mskll rather than several instructions
    		of load and an and instruction.  This could be extended
    		to more masks.
