If the scan phase has completed, you can:

1. interrupt whatever's running
2. mv bulklog bulklog.old
3. update tree
4. run bulkbuild-restart

It will reuse scan results from bulklog.old if possible -- only
rescans the packages affected by files that have changed.

(Of course, if bsd.pkg.mk changed then it rescans everything, but
that's part of why, e.g., we don't do infrastructure pullups on
release branches.)
