wc.db is always opened. In fact, it *must* be to look up any pristine
information. Opening that database is the slowest operation. From that
point, things are very fast.

For simplicity's sake, I would recommend an initial solution using
wc.db for the metadata. You could then write a test to see whether a
custom format would significantly outperform sqlite, and discussion a
change at that point.

IOW, do not "prematurely optimize". Go with the straightforward
sqlite-based solution and test/validate the speed in a future review.
