f8387af262 Issue #4688: Add a heuristic so that tuples and dicts containing only 
untrackable objects are not tracked by the garbage collector. This can
reduce the size of collections and therefore the garbage collection overhead
on long-running programs, depending on their particular use of datatypes.

(trivia: this makes the "binary_trees" benchmark from the Computer Language
Shootout 40% faster)

f35f8044e4 Rewrite Py_ARITHMETIC_RIGHT_SHIFT so that it's valid for all signed 
integer types T, not just those for which "unsigned T" is legal.

efc82f7e8e Issue #4258: Use 30-bit digits for Python longs, on 64-bit platforms. 
Backport of r70459.

68d6852006 Backport r69961 to trunk, replacing JUMP_IF_{TRUE,FALSE} with 
POP_JUMP_IF_{TRUE,FALSE} and JUMP_IF_{TRUE,FALSE}_OR_POP. This avoids executing
a POP_TOP on each conditional and sometimes allows the peephole optimizer to
skip a JUMP_ABSOLUTE entirely. It speeds up list comprehensions significantly.

2ffb26fb83 Issue #5260: Various portability and standards compliance fixes, optimizations 
and cleanups in Objects/longobject.c.  The most significant change is that
longs now use less memory:  average savings are 2 bytes per long on 32-bit
systems and 6 bytes per long on 64-bit systems.  (This memory saving already
exists in py3k.)

a40d573664 #3720: Interpreter crashes when an evil iterator removes its own next function. 
Now the slot is filled with a function that always raises.

41fbae1ac9 Oops. Need to check not only that HAVE_DECL_ISINF is defined, but also 
that it's equal to 1.  (If isinf isn't defined, HAVE_DECL_ISINF is
defined to be 0, rather than being undefined.)

d4ae97bc38 #3668: When PyArg_ParseTuple correctly parses a s* format, but raises an 
exception afterwards (for a subsequent parameter), the user code will
not call PyBuffer_Release() and memory will leak.

0668c62677 Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to 
match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
mechanism. In the process, fix a bug where isinstance() and issubclass(),
when given a tuple of classes as second argument, were looking up
__instancecheck__ / __subclasscheck__ on the tuple rather than on each
type object.

0470bab697 Issue #2620: Overflow checking when allocating or reallocating memory 
was not always being done properly in some python types and extension
modules.  PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
all been updated to perform better checks and places in the code that
would previously leak memory on the error path when such an allocation
failed have been fixed.
