Maeyanie	2e1fc25543	Fix 'Failed to malloc ckbuf in hash_search2' with very large files. ... lrzip was trying to malloc() enough memory to fit the entire length of file it was going to hash, instead of just the size of one chunk.

Con Kolivas	704d7b5eb6	There is no point using a thread on the last checksum update, nor to add the value to cksum_limit.	2012-03-11 12:22:35 +11:00
