I'm working on ioWakeUp() right now. Currently, I'm thinking
posting a dummy event to the X input stream may be best for the
X11 vm, specifically the NoExpose event

The windows VM seems to take a similar approach, from what I can
guess about what SetEvent() is

Are you working on a mac port of hydra? I'm working on a linux
port, but I havn't yet posted my code anywhere. I implemented
the mutex stuff via pthreads; hopefully correctly.
