 * if connect failed (conn refused) set state to connected and call internalclose, to get closed handler (instead of fdclose)
-* (lcore) if closing the fd's in internalcose, set fd's to -1 because closing an fd makes it invalid

 beware (20030927)
 * fixed: on connect failed, tried to close fdhandle's which were already set to -1, added check
