-------------------------------------------------------------
Since CompressedPoolingSegmentedFile is gone we will need a sure way to retest
CASSANDRA-9240.
The results just after a rebase are not that good:
{code}
Mean latency (one none running in foreground with -Xms500M -Xmx500M -Xmn50M,
inserting 200k and reading back 50k):
TRUNK insert 7.2
TRUNK read 8.7
TRUNK read after restart 16.4
8897 insert 6.8
8897 read 16.6
8897 read after restart 22.3
{code}
