Yeah, that too. I think it's all good now, but please test.

One thing I was wondering was whether the stat-wrong-file problem
could explain the buildfarm failures that we thought were evidence
of a portability issue. I was tempted to re-enable the #ifdef NOTYET
code, but didn't want to pull that trigger while there were other
problems outstanding.

At least I havent seen any of the problems pointed out in "fsync fun".

I unfortunately dont think so. The mkdir above should not have been bothered
by the stat issue - especially as it was only introduced by the commit to
disable the fsyncing.

That one actually was my idea/code and intentional with the idea to error out
at one more place if anything goes wrong in the copy loop - I could not think
of any race issues created by that which were not there before.
On the other hand its unlikely to catch anything so I dont mind.
