All changes since 0.2.2 to _poll_task, dir_size, and get_md5 (window_timeout,
_poll_oneshot, start_and_poll_immediately) are reverted. The 0.2.2 behaviour
worked reliably for small directories and is the last known-good baseline.
The remaining known limitation (occasional 599 on large directories) is
documented in SPEC.md. Retry the operation as a workaround.
