I don't really understand the above hash table usage output. It looks like
positions stored in the HT's, as my HT-size is 200Mb, and I guess one number
gives the amount being stored, the other what's being stored minus the positions
wiped from the HT because they aren't uninteresting. But I don't know for sure.
