probe now checks a series of consecutive, adjacent key/hash pairs before
continuing to make random probes through the hash table. This exploits
cache locality to make collision resolution less expensive.
The collision resolution scheme can be described as a hybrid of linear
probing and open addressing. The number of additional linear probes
defaults to nine. This can be changed at compile-time by defining
LINEAR_PROBES to be any value. Set LINEAR_PROBES=0 to turn-off
linear probing entirely.

* The interpreter starts about 30% faster. A couple of measures lead to the
speedup. The interpreter loads fewer modules on startup, e.g. the :mod:`re`,
:mod:`collections` and :mod:`locale` modules and their dependencies are no
longer imported by default. The marshal module has been improved to load
compiled Python code faster.
