Jonathan Ellis updated CASSANDRA-2950:

Attachment: 2950-v2.txt
v2:

// Bonus bonus: simply forceFlush of all the CF is not enough, because if
// for a given column family the memtable is clean, forceFlush will return
// immediately, even though there could be a memtable being flush at the same
// time. So to guarantee that all segments can be cleaned out, we need
// "waitForActiveFlushes" after the new segment has been created.

> Data from truncated CF reappears after server restart
