	The schedd should not crash if one of its jobs is (improperly)
matched to a slot with which the schedd can not communicate.  That being 
said, CCBClient::ReverseConnectCallback should only be being called after 
the reverse connection /succeeds/, so something strange is going on.

	Could you send me the schedd log from before the stack trace? 
(If you can reproduce this easily, it'd be great to get the log with
SCHEDD_DEBUG set to "D_NETWORK D_FULLDEBUG".)  Thanks.
