multiget_slice calls do not close files resulting in file descriptor leak
-------------------------------------------------------------------------

                 Key: CASSANDRA-1188
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1188
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.7
         Environment: Ubuntu 10.04
            Reporter: Matt Conway


Insert  1000 rows into a super column family. Read them back in a loop using multiget_slice.
Note leaked file descriptors with lsof:
lsof -p `ps ax | grep [C]assandraDaemon | awk '{print $1}'` | awk '{print $9}' | sort | uniq
-c | sort -n | tail -n 5

Looks like SSTableNamesIterator is never closing the files it creates via the sstable ...?

This is similar to CASSANDRA-1178 except for use of multiget_slice instead of get_slice
