Yes, I think I'll actually change a bit how that function works. It
almost always needs to create only the last directory, so I'll just
start checking the existence from the second-last directory in it and
start going down until one is found.

Not really, there could be race condition when two sessions try to
create it at the same time (however unlikely that is).
