--------------------------------------------------------------------
This is happening because of bug in the way deleted rows are [not] interpreted
once they leave the memtable in the CFS.getRangeSlice code.
CFS.getColumnFamily doesn't exhibit the bug, but the codepath is pretty
different.
I've got a fix that addresses standard columns, but it breaks a few of the
nosetests for super columns. Looking into that now.
