NFS does transactions - including figuring out if the data will fit - on
file close. It does that for real data so I'd relax. With hard disks we
don't even complete a set of actions on close they just float around for
a bit and get committed (but if there is a media failure you lose if you
didnt commit them first via fsync etc)

The two file problem then turns into the "which transaction of the two
done in parallel" problem.

Agreed
