Comment(by andrea):

 I've written a small non-blocking connect() test program which I will
 attach, and made observations.  On both Linux (kernel 3.9.1, x86-64) and
 OpenBSD 5.2 on x86-64, the output is as follows, which does not reproduce
 the presumed behavior if nickm's hypothesis on the cause is correct:

 connect() gave EINPROGRESS
 About to select()...
 The socket has become writeable according to select() (returned 1)
 Async connect() succeeded
 Socket closed
