This is pushing the problem into the wrong place, viz the lowest-level
file access routines, which will now all have to know about
.notcommitted status. It also creates race conditions --- think about
backend A trying to commit file 1234 at about the same time that
backend B is trying to flush some dirty buffers belonging to that file.
But most importantly, it doesn't handle the file-deletion case.
