Ok :-)
I've been able to confirm the difference is in connect() error
codes. On Linux, repeated connect() calls on the same non-blocking
socket return EINPROGRESS as long as the connection is pending,
then 0 exactly once, then EISCONN. FreeBSD (and SunOS) return
EISCONN instead of 0 when the connection is completed.
I have to improve my fix somewhat before I send it to you for
commit, so that it ignores EISCONN only when in non-blocking mode.
It still won't not be entirely correct because it should ignore
EISCONN exactly once and I have no idea how to achieve that simply.
Anyway, it's probably not desirable to have a 100% Linux behaviour
on that one, as the code would be needlessly twisted :-)
