I probably should have mentioned that this needs to be a persistent
store, hence my patience with trying all manner of seemingly weird things.
If this were just an in-memory structure an array would be great, but of
course any means of converting arrays to and from disk are
computationally expensive.
Worse, my aim here is to run all this in the most stringent of
environments: a CGI, where the app must initialize, run, return a
result, and die, all in as small a fraction of a second as possible.
