Yes, and if I've got the energy today, I might try and understand
what was going wrong on win98.  AFAICT the socket was being left
non-blocking but since the fhandler thought it was blocking, this
wasn't generally visible.  Perhaps *0 on NT systems is != 0 but on
9x systems it's == 0.

London's promised rain every day until the end of the weekend at
the earliest so I might yet have the opportunity to look more at
this :-(
