Nothing replaces a read-only file on Windows, neither a rename over it nor an in-place write, so the opt-in that keeps a read-only config saveable clears the attribute first; without that the test for it could not pass there. A failed config write still leaves the flag dirty, as before this change, but the next attempt waits ten seconds, so the idle handler does not repeat a hopeless write on every event. A file moved aside by a refused rename can be the only copy left if the process dies in between, so the sweep puts such a file back when its original is missing rather than removing it, and the directory-only errors that could only come from a directory target no longer trigger the move-aside at all. The sweep after a write runs only under the data dir and at most once an hour per directory, so a batch of saves does not read the directory once per file and an export into a user's folder never reads that folder. A lock holder that never lets go doubles the cool-down for each timeout in a row, up to five minutes, instead of costing a stall every ten seconds for good.
