I also expect kernel bug..

I've run into same problems in RH
(https://bugzilla.redhat.com/show_bug.cgi?id=427629). Would it be
possible send (me or here) stack traces where exactly named hangs? It
will point us where problem is. Mark's patch also point me that
internal_connect functions uses errno directly (something like switch
(errno) statement etc.). Not sure if something modifies errno and
socket code has unexpected behavior. Code should start use statements
like

err = errno;
switch (err) ...

instead use errno directly.
