Indeed I was not supplying the 3rd and 4th arguments to tcp-connect, 
which is why I was a little suprised.  Someone suggested offlist that I 
might be running out of local ports, so I wrote some code to track the 
number of ports I open.  Unfortunately it doesn't open more than about 
4000 before the exception occurs.  The number changes each time I run it.

The problem comes and goes, so I'll work on getting a test case together.
