I had a look over the patches (and refreshed my memory of what `xdl_classify_record()` does), and they look good. Having said that, I would love to increase my confidence by backing up the patches with a sort of stress test. Do we have anything like that? I guess not, a `git grep histogram t/` did not really turn up anything promising, p4000 does not even validate the output... Thanks, Dscho
