> 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..
