------------------------------------------------------------------

Do people generally configure their systems to have enough space in /tmp for 
the whole Cassandra heap?  I guess /tmp is generally the best place though.

> We should be able to designate the path location to put any perf dumps that 
> are performed. By Default with this not set the perf dump can occur on the 
> root disk and fill the drive. 
> Should be able to solve this by simply inserting JVM_OPTS="$JVM_OPTS 
> -XX:HeapDumpPath=<path to dir>" into cassandra-env.sh as a default option 
> available and set.
