Review Comment:
I don't think we can explicitly force a GC, in the test that I performed, it
required the FS instance to be left alone in a separate thread and after
sleeping for some time, we can use `System.gc()` which only points/suggests a
GC, which did call the `finalize()`, however, I am not sure if this would work
in every system per se, since it would depend on the resources available as
well at the time.
