I'd discourage this - if you change something in the same object as the
media, then the object is appended again to the ZODB, which will cause
unneccessary bloat.  I'd either have your method update the catalog - you
could create a new index for the download count - or have separate
associated objects for each file.  Perhaps the FSCounter, which is a kind of
page counter, or ThreadSafeCounter.

Catalog searches don't return the object, but a kind of reference to it -
check the zope book for details.
