I know there is some sort of cache, somebody was having a problem with
attachments which worked for a little while then disappeared. It turned
out the max_packet_size was too small and the cache was holding the
pictures for a while.

I wonder why it's possible to attach oversized photo (>1Mb), but
impossible to delete it (when recycle bin is enabled). I have a
hypotesis that there is a write-back cache.
This cache makes it possible to upload 3.5Mb photo, but it fails to
write it into a permanent store because of MySQL restriction.
Eventually, write-cached item becomes inaccessible.
