It causes a deadlock on ReactOS because the DLL loader unloads msafd.dll which
frees a critical section that protects the socket list. In the closesocket()
call, it tries to enter the critical section again to remove the socket, but
the critical section is invalid so it deadlocks. This causes any apps that use
wininet.dll to deadlock on close (until the lock is forcibly broken after the
critical section timeout elapses). I'm trying to avoid simply hacking around
the issue, so a real fix gets created for both WINE and ReactOS. If you've got
any ideas, I'd be happy to give it a shot and upstream it to you guys if it
works.
