well, i'll continue my experiments then, to see how high i can raise
the cache without problems. i finally hit a crash at 1.9GB, unfortunately,
so my theory about a 2GB upper bound is now dead in the water. :)

another consideration is, how high should a cache be for a given
quantity of data? should i reasonably expect that i should be able to
cache the entire filesystem, so venus can maintain somewhat of a local
disk copy of everything, or should i think of it more as a true cache
of the data?

i currently have 19GB of data, so a 250MB cache probably isn't too
shabby. though, a larger cache has saved me in situations when
codasrv dies or becomes unreachable.

tradeoffs, tradeoffs.

i also find it hard to believe. our entire dataset is content uploaded
via web forms, with little or no direct human interaction. there are
no extra links, hard or soft.
