To be honest, I don't know that it does. [Will report back later.]

Two points though:

a) This could doesn't alleviate the needs for dirmod.c, as far as I'm aware.
That seems to be there for a different reason, namely that there appears to
be some timing issue between creating a file and issuing an unlink/rename.

b) Do we have a case where rename's can block because of the file being held
open by another process? I haven't tripped over this yet...

Cheers,
Claudio
