24 Piotr Szymaniak asked me about lbzip2, and I bounced the question over
25 to my friend. He didn't investigate it deeply; it crashed (OOM or
26 something else, I don't know) when he tried it on a large file. Could
27 have been from 2GB to 2TB, from what he has laying around. I don't
28 know; I didn't get that one in writing. :)

31 no complaint. :)
