This improves speed by about 5.6% for me.

    The problem is in sre_compile.py: the call to
    _compile_charset near the end of _compile_info forgets to
    pass in the flags, so that the info charset is not compiled
    with re.U. (The info charset is used when searching to find
    the first character at which a match could start; it is not
    generated for patterns beginning with a repeat like '\w{1}'.)

Need to make sure that preprocessor directives start in first column.
This means we can't indent code which has preprocessor directives,
nor have a space between [ #include for example.

packages can check that extension modules are built for the right type
of python. Current values can be static, framework, shared and cfm (for
completeness, for MacPyton-OS9).

Closes bug #691889. The reporter suggests backporting this to 2.2.3
and I think I agree.

On a 64-bit machine, a dictionary could contain duplicate int/long keys
if the value was > 2**32.

a serious slowdown when loading dynamic modules that depend on large shared
libraries or frameworks.

Don't bother testing os.getlogin() if we aren't running from a tty (terminal)
It fails when run without a tty (e.g., when run from cron).

Also use True/False instead of 1/0 for symlink flag.

Subsumed times() into repeat().
Added cycle() and chain().

called to find tb_lineno -- even if Py_OptimizeFlag is true.

So don't call it again when printing the traceback.

This still falls back to helpers in copy_reg for:
   - pickle protocols < 2
   - calculating the list of slot names (done only once per class)
   - the __newobj__ function (which is used as a token but never called)

test_nonrecursive_deep():  Reduced nesting depth to 60.

Not a bugfix candidate.  2.3 increased the number of stack frames
needed to pickle a list (in order to get implement the "list
batching" unpickling memory optimization new in 2.3).

seconds making the doc for get_completer marginally less minimal :)

is required for the chosen internal encoding in the init function,
as this seems to have a better chance of working under Irix and
Solaris.

Also change the test character from '\x01' to '0'.

This might fix SF bug #690309.

on the boxes I use.

is a window manager and we can connect to it, i.e. if it is safe to try
and put up windows.

As a side effect the first call will make the current process frontmost.

between str, unicode, UserString and the string module
as possible. This increases code coverage in stringobject.c
from 83% to 86% and should help keep the string classes
in sync in the future. From SF patch #662807

time.sleep(1) sometimes delays for fractionally less than a second
resulting in too short of an interval for C's time.time() function
to create a distinct seed.
