Actually, RelStorage has it's own cache cleanup code for the
database-stored blobs scenario. And by the looks of it, it does
trigger a blob cache cleanup (in a separate thread) during blob load.

Maurits, see blobhelper.py, BlobHelper.download_blob calls
BlobCacheChecker.loaded with check=True (the default). Try calling it
with check=False instead.
