In r3487 we had set the master listening sockets to
non-blocking in order to avoid locking up the server when select() returns
but accept() does not.  This sets the individual connection sockets to non
blocking as well.  Now, the individual sockets are set back to blocking mode.
This prevents certain network operations from barfing when running on
FreeBSD.
