I am just guessing, but the exception handler for the second case calls 
Unix.close on line 963, which could raise a further exception that would 
not get caught. Also some of the Unix.xxx calls before the begin..try 
block could raise an exception. The odd thing is you're getting 
Unix_error(_, "connect", _), i.e., as if the actual call to Unix.connect 
causes it. By the way, isn't error 38 "function not supported"? What 
does that tell us?
