Corinna showed me that this was a problem in my autoload code rather than
a problem with winsock.  That's comforting.  I guess I've grown too quick
to judge Windows.

I've checked in a fix and am regenerating a snapshot.  The fix consisted of
deleting a few lines of code so that's always nice...

Thanks for the test case.  It helped a lot in tracking this problem down.
