Then the specification (that YOU wrote) is unclear about that.

|

The specification of MOVE is (in this matter) the same as EXPUNGE. I can make
|
|
it clearer though.

|

Then EXPUNGE is not atomic, as You've stated earlier.

And what about the same filesystem?

You're stating claims without proper arguments so I don't care.

|
|
YOU are claiming that there are races so prove that there are.
|
|
|
|
I claim that there are pink elephants living on the dark side of Pluto that
|
|
will prevent those races. The burden of proof is on you to demonstrate that
|
|
there are no such elephants.
