---------------------------------------------------------------------

 INFO 15:42:52,690 Scrub of SSTableReader(path='/var/lib/cassandra/data/Wajam/WebsiteWajams-f-155-Data.db')
complete: 3271113 in new sstable

"3271113 in new sstable"... I'm not sure it's 3271113 what... Looks like "good rows" according
to the patch, might want to specify! :)

I think it's the first time I see this line tho so it's good news. Is there any way the "invalid
bloom filter, will rebuild it" line can only appear once per sstable ? I'm guessing its generating
useless IO writing about 1000 of those lines/second in the log!

This should be definitly included in 0.7.3 which hopefully will be released soon!

Good work guys, very appreciated :)
