Crash in afd.sys when a socket is closed while select() is waiting

Debug log and test program attached.
The program creates a listening socket and a thread calling select() on the socket with a 100 ms timeout inside a loop. After 250 ms, the socket is closed, while select() is still waiting, this leads to a crash.
(Another way to reproduce the bug: install python and run "python -m test.regrtest -v -s test_asyncore")
