OK, so you have one box where it's extraordinarily easy to provoke
problems with these test scripts.  Since the cause is unlikely to be
Windows (despite that all flavors of Windows appear to have bugs here,
they're pretty shy on most boxes), I'd suggest looking at 3rd-party
software you run on your laptop but not on other boxes.  For example,
software firewalls are a good candidate, and, e.g., I used to see
several "impossible socket problems" only when ZoneAlarm was active
(and I stopped seeing that when I stopped ZoneAlarm ;-)).  Anti-virus
and active anti-spyware programs can also create no end of mysterious
problems.
