[Pythonmac-SIG] WaitNextEvent and OS9

[Jack Jansen]

Maybe someone can help me with the following: under OS9 I'm noticing
that WaitNextEvent(), even with a zero timeout, will take more and
more time before returning, unless you frantically wriggle the mouse.

I noticed this while putting GUSI2 in Python, but some careful testing 
of old and new Pythons on OS8 and OS9 showed that this is probably OS9 
behaviour.

I think this might be some "intelligent" behaviour of MacOS (programs
that keep calling WaitNextEvent with low timeout values without
getting any events have the cpu taken away from them), but with Python 
calling WNE in the mainloop this is rather bothersome behaviour.

Does anyone know whether this guesswork is correct and, if so, if
there's anything I can do about it?
