Miller, who complained that its kurtosis was bad, and then fixed by
Lambert Meertens (author of the original algorithm) who discovered
that the mathematical analysis leading to his solution was wrong, and
provided a corrected version.  Mike then tested the fix and reported
that the kurtosis was now good.

Don't call normcase() in normpath() -- the filesystem just might be
case preserving...

Also, I just ran across a [possible] minor glitch
in the library documentation for site.py. It says:

"For example, suppose sys.prefix and
sys.exec_prefix are set to `/usr/local'. The
Python 1.5 library is then installed in
`/usr/local/lib/python1.5'. Suppose this has a
subdirectory `/usr/local/python1.5/site-packages'
with three subsubdirectories, `foo', `bar' and
`spam'..."

I think it should be:
"...Suppose this has a subdirectory
`/usr/local/lib/python1.5/site-packages' with..."

that was only causing confusing).  Add free(userpath) and
free(machinepath) statements to prevent some leaks.

(modified) and use that.

Some differences in the cleanup algorithm:

- Clear __main__ before the other modules.

- Delete more sys variables: including ps1, ps2, exitfunc, argv, and
even path -- this will prevent new imports!

- Restore stdin, stdout, stderr from __stdin__, __stdout__,
__stderr__, effectively deleting hooks that the user might have
installed -- so their (the hooks') destructors will run.

__stderr__.  These will be used by the import cleanup.

clear_carefully() used to do in import.c.  Differences: leave only
__builtins__ alone in the 2nd pass; and don't clear the dictionary (on
the theory that as long as there are references left to the
dictionary, those might be destructors that might expect __builtins__
to be alive when they run; and __builtins__ can't normally be part of
a cycle).

if the globals are the same.

Also, when creating a dummy builtins dictionary, add "None" to it,
just to be kind.
