Confirmed. This has been introduced by trying to get the WinSock event
driven accept thread-safe. This apparently doesn't work as expected.
To get that really right, a lot more has to be done. Since that's
nothing I'd like to rip apart before 1.5.20, I reverted all event
handling for accept and connect and returned to using select again, as
it was implemented until 1.5.18.
