For what it's worth, we noticed the same thread limitation phenomenon last December or January, but could never pin it on Cygwin and therefore didn't notify the list. The number of threads in our application is rather dynamic, so we never tracked the limit down to 52 threads, but that sounds about right. We even engineered code to get around this problem (by establishing a limited size thread pool and queueing work to the pool if all threads were busy). I just installed sp2 on w2k and the testsuite still fails. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/hh/winbase/prothred_4084.asp says: "The number of threads a process can create is limited by the available virtual memory. By default, every thread has one megabyte of stack space. Therefore, you can create at most 2028 threads. If you reduce the default stack size, you can create more threads."
