MemoryError during import

[jhuldtgren]

Trying to import an album results in a MemoryError, the reason seems to be that one of the candidates it finds on discogs is an album with 6666 tracks. Disabling the discogs plugin so this is not a candidate "fixes" it and lets the import proceed. While albums with that many tracks are not the norm, is there something which can be tweaked so beets can handle that?
