[Python-3000] refleaks and other errors

[Neal Norwitz]

That was mostly the first line of my message, although it was a bit terse. :-)

It's just a cmd line option to regrtest.py -R 4:3:
Everything else is the same.

The way I run it for test_grammar:

./python -E -tt ./Lib/test/regrtest.py -R 4:3: test_grammar

You can also pass "-R ::" instead of "-R 4:3:" however that takes
longer and generally doesn't help much.

Note that some tests that normally pass will fail (not the refleaks,
actually fail) with this option due to the test not cleaning up after
itself.
