Maybe you should study the code under discussion before making such
a proposal.
I did, and it does nothing of what I suggested. I am sure I can make the
Windows GIL
in ceval_gil.h and the mutex in thread_nt.h at lot more precise and
efficient.
This is the kind of code I was talking about, from ceval_gil.h:
r = WaitForMultipleObjects(2, objects, TRUE, milliseconds);
I would turn on multimedia timer (it is not on by default), and replace
this
call with a loop, approximately like this:
for (;;) {
r = WaitForMultipleObjects(2, objects, TRUE, 0);
/* blah blah blah */
QueryPerformanceCounter(&cnt);
if (cnt > timeout) break;
Sleep(0);
}
And the timeout "milliseconds" would now be computed from querying the
performance
counter, instead of unreliably by the Windows NT kernel.
