Just by the way, on that last point, we trained cfbot to watch out for
CI pass/fail in this account:
https://github.com/postgres/postgres/commits/master/
and then use the most recent pass as the base commit when applying
patches to make test branches. So if master is broken for a while, it
no longer takes all the cfbot runs with it. Mentioning just in case
anyone is confused by that...
As for what's happening... hmm, there are a few holes in the "shared
locking" stuff you get with the flags we use. For example you can't
unlink a directory that contains a file that has been unlinked but
someone still holds open. Doesn't seem to be the case here. But I
wonder if you can't rename("old", "new") where "new" is a file that
has already been unlinked (or renamed over) that someone still holds
open, or something like that...
