+tracemalloc
+-----------
+
+The new :mod:`tracemalloc` module (defined in :pep:`454`) is a debug tool to
+trace memory blocks allocated by Python. It provides the following information:
+
+* Traceback where an object was allocated
+* Statistics on allocated memory blocks per filename and per line number:
+ total size, number and average size of allocated memory blocks
+* Compute the differences between two snapshots to detect memory leaks
