Threading.Event w/ timeout veeeeeery slow on win32?

[chris liechti]

what is the timeout value?
i've had problems with time.sleep() when using values smaller than 20ms 
(0.02). I'm now using 30ms wich works fine.

it seems that windows has a time resulution of 10ms or worse...

(details: when i ran the old code with time.sleep(0.01) the program got 
very slow and the win NT4.0 taskmanager told that [File] Explorer is 
getting 30% of CPU power. this number must be totaly wrong because its an 
other process and my programm does not use files or any other things that 
would require the Explorer. moral: don't count on windows if it get near 
10ms )
