@ -132,9 +132,13 @@ A few performance enhancements have been added:
* The garbage collector tries to avoid tracking simple containers which
can't be part of a cycle. As of now, this is true for tuples and dicts
containing atomic types (such as ints, strings, etc.). Transitively, a dict
containing tuples of atomic types won't be tracked either. This helps brings
down the cost of full garbage collections, since it decreases the number of
objects to be considered and traversed by the collector.
containing tuples of atomic types won't be tracked either. This helps bring
down the individual cost of each garbage collection, since it decreases the
number of objects to be considered and traversed by the collector.
To help diagnosing this optimization, a new function in the :mod:`gc`
module, :func:`is_tracked`, returns True if a given instance is tracked
by the garbage collector, False otherwise.
