Close handlers and tidy up loggers by removing closed handlers - to avoid problems when run twice (SF #1002537)

unicodedata.east_asian_width().  You can still implement your own
simple width() function using it like this:
    def width(u):
        w = 0
        for c in unicodedata.normalize('NFC', u):
            cwidth = unicodedata.east_asian_width(c)
            if cwidth in ('W', 'F'): w += 2
            else: w += 1
        return w

or broken by basic ctype functions in 4.4BSD descendants.  This
will be fixed in their future development branches but they'll keep
the POSIX-incompatibility for their backward-compatiblities in near
future.

imputils Importer._process_result():
    remove name from modules dict if exec fails.

This is what all the builtin importers do now, new in 2.4.

scripts without modifying either the distutils installation or the
setup.py scripts of packages with which the new commands will be used.

Specifically, an option is added to distutils that allows additional
packages to be searched for command implementations in addition to
distutils.command.  The additional packages can be specified on the
command line or via the installation or personal configuration files
already loaded by distutils.

This closes SF patch #102241.

for the tests, and restored properly when done

possible that the callback-less flavors of the ref or proxy could have
been added during GC, so we don't want to replace them.

Will backport to 2.3.

Python was built with VC 7.1.

It's not the 100% solution -- it may not even be the 90% solution -- but
it does seem to help.

an initlog() (and initlog()'s docstring says "don't use this"!) This
allows test_cgi to be run repeatedly in a single run of the interpreter.

way to guarantee a deadlock on the next call!

If I've inadvertently done some damage to this test, sorry (but I don't
think I have).

Hard to believe it ever helped anything, and it hurts finding reference
leaks.

the case of __del__ resurrecting an object.
This makes the apparent reference leaks in test_descr go away (which I
expected) and also kills off those in test_gc (which is more surprising
but less so once you actually think about it a bit).
