False alarm, actually. My threaded CRC32 code was broken and was not
taking some of the last pages into account. I fixed that now in my code
and indeed CRC32 of the decompressed pages is the same as the one of the
pages before compression.

PS. We are going to lose about 10% of the the speed improvements by
introduction of CRC32 (which will only be used with compression). I
reckon it's still worth it.
