Subject: [PATCH] Clean up acceptance LevelDB temp dirs

Each psf-memo-db acceptance scenario opened an isolated LevelDB directory
but close() only closed the handles, so tmp/acceptance grew without bound
(found at 961 dirs / 293 MB). Delete the scenario dir in close() and sweep
tmp/acceptance at the start of the acceptance run.

By specifier.
