This is rather a different issue - while it's interesting to note the
comparisons, I don't see there being much in common between these two
issues.

In particular, for your implemenation, the 'server' on the unix side can
cause events.  As far as I understand it, this does not occour on
Windows Named pipes - they are standard SMB read and write requests,
just handled differently.

But yes, both of these things need to be dealt with...
