The only problem is how to detect the first connection. In a threaded
environment you'd have to perform locking in connectdb, which is
probably not going to fly.
>>but does it say something similar about shutdown?
From the WSACleanup docs:
"The WSACleanup function typically leads to protocol-specific helper
DLLs being unloaded. As a result, the WSACleanup function should not be
called from the DllMain function in a application DLL. This can
potentially cause deadlocks"
