Fix Version/s: None
According to the dev's list discussion (1) I've patched the CompactionManager to allow parallel compaction.
Mainly it splits the sstables to compact in the desired buckets, configured by a new parameter: compaction_parallelism with the current default of "1".
Then, it just submits the units of work to a new executor and waits for the finalization.
The patch was created in the trunk, so I don't know the exact affected version, I assume that is 0.8.
I'll try to apply this patch to 0.6.X also for my current production installation, and then reattach it.
