--------------------------------------------------------------------
Attached 7712_workaround.txt patch to set a {{tmp.dir}} property and use that
as a {{jvmarg}} in testlist. Tested this with and without passing in the
option with no problems - -the jvm also created my custom tmp.dir for me- (I
must have done a run with my tmp.dir already created - we do need to mkdir it).
This workaround provides us the ability to set the temporary data dir within
our git workspace, and since we are using {{git clean -xdf}} at the beginning
of every unit test run, this data will no longer accumulate.

> There are many unit test temporary files left behind after test runs. In the
> case of CI servers, I have seen >70,000 files accumulate in /tmp over a
> period of time. Each unit test should make an effort to remove its temporary
> files when the test is completed.
> My current unit test cleanup block:
> {noformat}
> # clean up after unit tests..
> rm -rf /tmp/140*-0 /tmp/CFWith* /tmp/Counter1* /tmp/DescriptorTest*
> /tmp/Keyspace1* \
