Are you using try:...finally:... inside your testcase methods? If so,
why not just move the cleanup invocation into your 'tearDown' for the
testcase class: at that point, the '-D' option to the testrunner will
stop you at the error, with the tearDown not yet called.
Or are you doing this in doctests? If so, move the code you are testing
into a real testing framework. ;)
