# Yes, slurping all the records at once consumes a lot of memory,
# but I want them to be sorted the way perl sorts them, not the
# way sqlite sorts them. That way, the index file looks more
# like one produced by PAUSE. Also, this is about twice as fast
# as using an iterator to read each record lazily.
