    This basically reimplements the logic in a way that I find much more
    understandable than the old code ported from MRI. This code is based on
    a combination of and the MRI source
    code, taking the most useful parts from both.

  1. Fix timing issue of Thread#kill and sleep

    ryoqun committed Sep 2, 2012
    In some cases, a thread isn't correctly killed by Thread#kill. If that is the
    case, Thread#join on that thread leads to the deadlock.
    Consider the following example:
        thread = do
        thread.kill # actually, don't kill
        thread.join # thread lives forever; deadlock
    Thread#kill does 2 things to kill a thread:
        1. prepares the thread to be terminated and
        2. wakes up the thread.
    Most of time, the wake-up is executed after the sleep in the killed thread.
    However, it is possible the wake-up is executed BEFORE the sleep in some rare
    cases. If that is the case, the wake-up does nothing because the thread is
    still waking up at that time. Then, the thread begins to sleep forever. As a
    result, Thread#join never returns.
    To avoid such a deadlock, Thread#sleep must check to terminate or not before
    actually sleeping. In addition, it must be asssured that the wake-up isn't
    executed AFTER the check BEFORE the sleep.
    The follwing diagrams illustrate the good and bad timings.
    Good timings:
        main thread  prepare - wakeup (no-op) |
        new thread                            | check - no sleep - terminate
        main thread                | prepare - wake-up |
        new thread   check - sleep |                   | terminate
        main thread        | prepare |       | wake-up |
        new thread   check |         | sleep |         | terminate
    Bad timing:
        main thread        | prepare - wake-up (no-op) |
        new thread   check |                           | sleep forever
    To fix the deadlock, this commit makes check_async be called before sleeping
    inside the park mutex.

  1. Renamed VMMethod to MachineCode.

    brixen committed Aug 28, 2012
    This was a difficult name choice but it is consistent with CompiledCode
    and (not yet used) SourceCode. The CompiledCode is an abstraction of
    computation that is the focal point around which much revolves. MachineCode
    is a representation of computation specialized for our (virtual) machine.
    While there is possible ambiguity against the idea of JIT'd machine code,
    our MachineCode is a proper data structure, not just the format of bits
    resulting from the JIT compilation process. Also, our MachineCode is properly
    scoped differently than any such class/concept in LLVM (or more generally,
    the JIT).
    Regarding naming of instances of MachineCode, the following rationale is used:
    * parameters/variables have been named 'mcode' since the use of the variable
      is elaborated by the surrounding code (ie making ambiguity less an issue)
      and long variable names can sometimes make code unweildy.
    * attributes/fields/accessors have been name 'machine_code' because they have
      less context to disambiguate.
