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
