This doesn't seem to be a likely error, but we've got the counter
anyway, so we might as well use it for an added bit of safety.
Please note that the first call to rename() is optimistic, and it is
normal for it to fail if there is a directory in the way. So bump the
total number of allowed attempts to 4, to be sure that we can still
have at least 3 retries in the case of a race.
