Jonathan Ellis updated CASSANDRA-3579:
--------------------------------------

    Attachment: 3579-fix-text.txt

Switching from <= to < means that getColumnFamily will now include tombstones for just-deleted column with gcgs == 0.

For clients this is harmless (since we drop tombstones in the coordinator after RR), but internal code needs to be more careful.  patch attached to have loadTokens expunge all tombstones.
