What Werner did was to force Python to garbage-collect all Python
objects that do not have any reference anymore (i.e., they are useless
and can be safely destroyed/removed to increase the resource
availability).
Quoting Fredrik Lundh very useful help pages:

"""
Python uses reference counting to keep track of when to get rid of
objects; as soon as the last reference to an object goes away, the
object is destroyed.

Starting with version 2.0, Python also provides a cyclic garbage
collector, which runs at regular intervals. This collector looks for
data structures that point to themselves, and does what it can to
break the cycles.

You can use the gc.collect function to force full collection. This
function returns the number of objects destroyed by the collector.
