[Python-Dev] Updated PEP 454 (tracemalloc): no more metrics!

[Victor Stinner]

Hum, timestamp and traceback_limit attributed of GroupedStats can also be
removed, they are just of the same attribute of the Snapshot class and
GroupedStats is created from Snapshot.group_by().

An option is to modify GroupedStats to inherit from dict, so
GroupedStats.stats would be GroupedStats directly.

> * should GroupedStats.statistics() and GroupedStats.compare_to()

The result is a list which can be bigger than 100,000 items. The question
is if it would inefficient to sort the list twice.

Another option is to replace sort parameter with a new sort_key parameter
(callable), passed to list.sort as the ke parameter.
