Description

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
