Stop() does not clean up CachePath directory

[nitaysol]

When using a custom CachePath calling Stop() shuts down
the postgres process but does not remove the cache directory.
Over
repeated test runs, these directories accumulate in the CachePath and currently I clean it manually.

Start() already cleans up runtimePath on each invocation, but there
is no equivalent cleanup for CachePath on Stop().

Is this intended ?

I also understand its related to runtimePath not being cleaned as the tar is being extracted into it.
So if I run multiple tests which run in parallel i can be ending with a lot of disk usage, correct me if im wrong :)
