It's been around three or four years since I encountered that, so the
details are pretty vague now.... I was writing an instant messaging server
that spawned a thread for every incoming connection (not the best way, but
it was my first attempt at network programming, multithreading and my
first Python program to boot =). I was stress-testing my server and I had
an adjustable parameter limiting the number of threads allowed at any one
time. If I set this higher than, say 20 (highly questionable if that's
the number), NT would flake out (I think to the point of BSOD, but I can't
recall). Anyway, without changing any code, applying SP5 fixed it, and I
seem to recall that threading was one of the issues addressed in SP5.
