But the only case in which you'd have to run so many queries would be
when you have *none* of those activities installed.

I'd suggest dropping the size field from the listing then, if its
really taking too long.
(again, I feel the only realistic deployment scenarios make size
querying quick: school server hosts activities, or school server
webcache caches activities, so I'm not entirely convinced by your
argument)

I assume your code of reference is the 0.84 updater - the last
implementation of a microformat-based updater. If it's not, you should
certainly examine it closely. This updater behaves in the way I have
described.
