Hi,

After considering several possible solutions for implementing 
function timeout in WIN32 platform. it seems that there is no 
reliable solution based on async. canselation. Here what I propose:

1. As usual we need Timer thread. It could be new thread started 
every time we need to run test case with timeout. It could be current 
thread while test case run in new one. It could be permanent thread 
responsible for timeouts.
2. Implementation will assume *synchronous* cancelation. This mean 
that when timeout occured Timer thread will set some 'timeout flag' 
which will be checked with every access to the framework. Now the 
user responcibility is to make sure that test case accessing 
framework frequently enough.
3. Timer thread will set internal timeout in, let say, 1 second while 
it will wait for current test case to complete. If timeout will 
occured. we consider this as a fatal error and abort testing.

What do you think?
