Title: clearing up and down pull request...as requested,..

...e)

we have infinite recursion prevention already covered
also we add an optional param to clearInstancePool. if passes as true it will clearAllReferences(true) on every
instance before clearing it.

Both these options together are useful when trying to stop memory leaks due to circular references during logn running jobs dealing with a lot of data.
