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.

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).

comma expression in listpop() that was being returned.  Still essentially
unused (as it is meant to be), but now the compiler thinks it is worth
*something* by having it incremented.

- fix broken assert statement; should just raise

have differing refcount semantics.  If anyone sees a prettier way to
acheive the same ends, then please go for it.

I think this is the first time I've ever used Py_XINCREF.
