A modest suggestion for unittest.py

[Rich Harkins]

Would it be okay with everyone if there was some option added to the
TestProgram (invoked by default when using unittest.main()) so that it does
not perform a sys.exit() when it is done running tests?  This would make it
easier to run some tests and then drop through to the interpreter with -i.
Better yet, it would be nice if the interpreter mode had direct access to
the test cases (where the tests are exposed to globals()) for easier
probing.
