* ``bzrlib._static_tuple_c.StaticTuple`` is now available and used by
77
the btree index parser. This class functions similarly to ``tuple``
78
objects. However, it can only point to a limited collection of types.

(Currently StaticTuple, str, unicode, None, bool, int, long, float, and
80
not subclasses). This allows us to remove it from the garbage collector
81
(it cannot be in a cycle), it also allows us to intern the objects. In
82
testing, this can reduce peak memory by 20-40%, and significantly
83
improve performance by removing objects from being inspected by the
84
garbage collector. (John Arbash Meinel)
