10.9.4 seems to have resolved this "issue". I'm guessing that when scanning for new and updated files in 10.9.0-10.9.3 it was polling MusicBrainz for more than what was needed. If you don't add any tracks to your library and perform a scan, it shouldn't need to go to MusicBrainz at all, and even then the number of requests should be minimal for not needing any new metadata.
My full library scans are now taking less than a minute, so everything is working as it was pre-10.9.
