This is a known bug that has been around for some time. It only happens on
SMP hardware, which I don't have yet, so there have been a couple blind
attempts at a fix that have failed.
My new SMP motherboard and processors and etc. arrive next week, so
hopefully soon I'll be able to better understand the problem and then come
up with a solution. (Just don't tell my wife that all this new hardware
($$$) was only bought to squash a bug in free software...)
NT and Win2k users can work around the problem by telling the OS to keep the
process on just one processor:
import win32api, win32process
cp = win32api.GetCurrentProcess()
You can keep track of the bug here:
