Skip this test created by r60830.

They still remain fragile.

For example, a call to assertEqual currently does not make any allocation
(which surprised me at first).
But this can change when gc.collect also deletes the numerous "zombie frames"
attached to each function.

in the config dialog would cause non-Python files to be colored as if they
were Python source; improve use of ColorDelagator.  Patch 1334. Tal Einat.

Also correct a possible crash using ABCs.

This change is exactly the same as an optimisation
done 5 years ago, but on slot *access*:

  * place_summary_first copies the regrtest summary to the front of the file
    making it easier to scan quickly for problems.

  * count_failures gets the actual count of the number of failing tests, not
    just a 1 (some failures) or 0 (no failures).

In PyNumber_ToBase, changed from an assert to returning an error when PyObject_Index() returns something other than an int or long.  It should never be possible to trigger this, as PyObject_Index checks to make sure it returns an int or long.

Thanks to Thomas Herve for the fix.

Fixed repr() and str() of complex numbers. Complex suffered from the same problem as floats but I forgot to test and fix them.

Use a static and interned string for __subclasscheck__ and __instancecheck__ as suggested by Thomas Heller in #2115

Implemented Martin's suggestion to clear the free lists during the garbage collection of the highest generation.

self._numerator and self._denominator. This speeds abs() up from 12.2us to
10.8us and trunc() from 2.07us to 1.11us. This doesn't change _add and friends
because they're more complicated.

  ./python.exe -m timeit -s 'from fractions import Fraction' 'Fraction(3)`
31.7 usec/loop -> 9.2 usec/loop

  ./python.exe -m timeit -s 'from fractions import Fraction' 'Fraction(3, 2)'`
27.7 usec/loop -> 9.32 usec/loop

  ./python.exe -m timeit -s 'from fractions import Fraction; f = Fraction(3, 2)' 'Fraction(f)'
31.9 usec/loop -> 14.3 usec/loop

works.

Thanks to Jeroen Ruigrok van der Werven for the fix.

  ./python.exe -m timeit -s 'from fractions import Fraction; f = Fraction(3, 2)' 'isinstance(3, Fraction); isinstance(f, Fraction)'
from 12.3 usec/loop to 3.44 usec/loop and
  ./python.exe -m timeit -s 'from fractions import Fraction' 'Fraction(3, 2)'
from 48.8 usec to 23.6 usec by avoiding genexps and sets in __instancecheck__
and inlining the common case from __subclasscheck__.

test_fractions.py.  This should have been part of the name
change from Rational to Fraction.

classmethods instead of staticmethods.

Remove Fraction.to_continued_fraction and
Fraction.from_continued_fraction

implements the chunked encoding incorrectly.
Will backport to 2.5.
