And given that it's a relatively small piece of the overall puzzle, it
need not be much more of a headache to maintain than the various
platform specific pieces inside the Python core are (e.g., the
threading portions).  Probably less, since I expect CPUs and/or things
with impact on the stack switching may change less frequently than
OS/platforms.  In any case, it seems like it's worth the tradeoff,
especially if it makes it Python version independent (or easily
trackable).
