Yep - I completely agree Explorer is braindamaged. That's probably
the worst of the lot :-).

If it only happens on AIX, it's not a Samba code logic problem, that's
what I mean. I doubt modifying compiler flags will do anything about
actions taking seconds to resolve - that's almost certainly a system
problem (ie. JFS on AIX).
