Because of the memory usage?

Here's a thought: instead of storing the packablerevs in a Python
dictionary, we could use a separate (temporary) Berkeley table that's
/only/ used for packing.  We already acquire a pack-lock to prevent
two threads from packing at the same time, so this would protect the
pack database as well.

It might not be any faster, but it ought to be much more memory
friendly.
