Comment 2 for bug 772471

I am starting to suspect that this has something to do with, not sockets, but instead with the win32 thread handle not being closed, because there are two of them (two threads) for each client. As I recall, with the win32 thread creation API EPICS is using, _beginthreadex, the handle is implicitly closed when the thread function returns, but I will need to investigate in the debugger.
