 Hi,
 
 The problem occurs after some number of calls to sockout.  Here is
 an example done on my machine.  The output of uname -a is:
 
 FreeBSD mongo.pbspro.com 4.3-STABLE FreeBSD 4.3-STABLE #3: Thu May 10 16:27:47 PDT 2001     proett@mongo.pbspro.com:/usr/src/sys/compile/BONGO i386

 mongo# ./sockout 4711

 The third call to sockout was not detected by sockin which continued
 to periodicaly timeout until I hit ^C.  I ran netstat while it was in
 this state and got:
 
 tcp4       0      0  localhost.1023         localhost.4711         SYN_SENT
 tcp4       0      0  localhost.4711         localhost.1023         TIME_WAIT
