> From the work in CASSANDRA-15170, reviewing the output from lsof shows that file descriptors from closed clusters are still open after all instance objects and the instance class loader have been garbage collected.
> To run sustained fuzz/property based testing, file handle leaks need to be minimized.
> Reproduce by running ResourceLeakTest.looperTest included as part of CASSANDRA-15170 and look at `build/test/*-lsof-final.txt`
