That is correct. You need two major compactions and no newer Puts in order to
remove family delete markers when KEEP_DELETED_CELLS is enabled. This only
affects family delete markers.
When I made that patch I could not find a good way around this. If you did a
2nd major-compaction before you added newer puts they'd be removed. There is a
(long) explanation in HBASE-4536.
