Compaction doesn't clear out expired tombstones from SerializingCache
---------------------------------------------------------------------

                 Key: CASSANDRA-3921
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3921
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 0.8.0
            Reporter: Jonathan Ellis
            Priority: Minor
             Fix For: 1.1.0


Compaction calls removeDeletedInCache, which looks like this:

{code}
.   public void removeDeletedInCache(DecoratedKey key)
    {
        ColumnFamily cachedRow = cfs.getRawCachedRow(key);
        if (cachedRow != null)
            ColumnFamilyStore.removeDeleted(cachedRow, gcBefore);
    }
{code}

For the SerializingCache, this means it calls removeDeleted on a temporary, deserialized copy,
which leaves the cache contents unaffected.
