Actually, it turns out that NT is trying to handle this
by deleting the file on write fail. The problem is in
our handling of setting the delete on close semantics.

I'm currently writing test code in smbtorture to run
against a W2K server so we can "do what it does". Expect
a checkin to fix this in the next day or two (this is a 
*subtle* problem).


Buying an operating system without source is like buying
a self-assembly Space Shuttle with no instructions.
