yeah, i was expecting a hit of 50 queries at once, but after that
there should be zero for that set.

does anyone have any example code when dealing with lists like this?
just build an array of IDs, and then do some sort of
asset_multiget($array) which does a cache_multiget of the IDs, ...
hmm. that gets confusing then. because i will need to track
hits/misses. that's why i think i liked the single row approach,
because hits and misses can be mixed and i am none the wiser...

i'd be curious (and grateful) to see anyone's approaches which seem
appropriate to deal with a multiple get/multiple row matches...

thanks!
