[Python-Dev] windows buildbot failures

[Neal Norwitz]

The windows buildbot slaves (cygwin too) are still having problems
with the DLL being in use when we start compiling so the compile
fails.  clean.bat is not called afterwards based on the buildbot log. 
I don't know if clean fixes the problem.  If it does, would this patch
fix the problem:

If the patch won't fix the problem, is there something else we can do
to ensure the python DLL is no longer used regardless of whether the
previous test passed or not?  If we can get the process handle, can we
can subprocess.TerminateProcess()?
