Added a new macro, Py_IS_FINITE(X). On windows there is an intrinsic for this and it is more efficient than to use !Py_IS_INFINITE(X) && !Py_IS_NAN(X). No change on other platforms

Heavily fiddled variant of patch #1442927 : PyLong_FromString optimization.
...
``long(str, base)`` is now up to 6x faster for non-power-of-2 bases. The
largest speedup is for inputs with about 1000 decimal digits. Conversion
from non-power-of-2 bases remains quadratic-time in the number of input
digits (it was and remains linear-time for bases 2, 4, 8, 16 and 32).
Speedups at various lengths for decimal inputs, comparing 2.4.3 with
current trunk. Note that it's actually a bit slower for 1-digit strings:

Added a slew of test for string replace, based various corner cases from
...
the Need For Speed sprint coding. Includes commented out overflow tests
which will be uncommented once the code is fixed.
This test will break the 8-bit string tests because
"".replace("", "A") == "" when it should == "A"
We have a fix for it, which should be added tomorrow.

Bug #1334662 / patch #1335972 : int(string, base) wrong answers.
...
In rare cases of strings specifying true values near sys.maxint,
and oddball bases (not decimal or a power of 2), int(string, base)
could deliver insane answers. This repairs all such problems, and
also speeds string->int significantly. On my box, here are %
speedups for decimal strings of various lengths:
length speedup
------ -------
1 12.4%
2 15.7%
3 20.6%
4 28.1%
5 33.2%
6 37.5%
7 41.9%
8 46.3%
9 51.2%
10 19.5%
11 19.9%
12 23.9%
13 23.7%
14 23.3%
15 24.9%
16 25.3%
17 28.3%
18 27.9%
19 35.7%
Note that the difference between 9 and 10 is the difference between
short and long Python ints on a 32-bit box. The patch doesn't
actually do anything to speed conversion to long: the speedup is
due to detecting "unsigned long" overflow more quickly.
This is a bugfix candidate, but it's a non-trivial patch and it
would be painful to separate the "bug fix" from the "speed up" parts.

needforspeed: use append+reverse for rsplit, use "bloom filters" to

speed up splitlines and strip with charsets; etc. rsplit is now as
fast as split in all our tests (reverse takes no time at all), and
splitlines() is nearly as fast as a plain split("\n") in our tests.
and we're not done yet... ;-)
