Right, 7.2b4 passes *all* tests both parallel and sequential on Windows 2000
Server. 

On XP Pro, and by the sounds of it, any other non-server releases of
Windows, parallel tests will fail randomly due to Winsock backlog limit of 5
on these systems (as pointed out by Jason Tishler and documented in
FAQ_MSWIN).
