Not sure if these are the correct values, but save_stdout has to be set before its usage...

Refactor if/elif chain for clarity and speed.  Remove dependency on subclasses having to implement _empty and _full.

exec call and when creating a recursive instance.

The duplication is intentional -- this paragraph is in a section
describing additions to the sys module, and there's a later section
that mentions the switch.  I think most people scan the what's-new and
don't read it in detail, so a bit of duplication is OK.

precision. This has been discussed at http://bugs.python.org/issue1682. It's
useful primarily for teaching, but it also demonstrates how to implement a
member of the numeric tower, including fallbacks for mixed-mode arithmetic.

I expect to write a couple more patches in this area:
 * Rational.from_decimal()
 * Rational.trim/approximate() (maybe with different names)
 * Maybe remove the parentheses from Rational.__str__()
 * Maybe rename one of the Rational classes
 * Maybe make Rational('3/2') work.

empty() and full().

Orignal patch (without tests) by Leif Walsh.

Fix 1698398:  Zipfile.printdir() crashed because the format string expected a tuple object of length six instead of a time.struct_time object.

Now that I've learnt about structseq objects I felt like converting sys.float_info to a structseq. It's
readonly and help(sys.float_info) explains the attributes nicely.

Added new an better structseq representation. E.g. repr(time.gmtime(0)) now returns 'time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=0)' instead of '(1970, 1, 1, 0, 0, 0, 3, 1, 0)'. The feature is part of #1816: sys.flags

Slots inheritance is very different from OO inheritance.
This code lead to infinite recursion on classes derived from StructType.

now that ctypes uses a more supported method to create types:

Method cache optimization, by Armin Rigo, ported to 2.6 by Kevin Jacobs.

ctypes takes some liberties when creating python types: it modifies the types'
__dict__ directly, bypassing all the machinery of type objects which deal with
special methods.  And this broke recent optimisations of method lookup.
Now we try to modify the type with more "official" functions.

#1550: help('modules') broken by several 3rd party libraries.

Tested with Python build: trunk:54235:59936M -- the reported error
occurs with Django installed (or with any __init__.py present on
the path that raises an exception), and such errors indeed go away
when this change is applied.
