[issue20746] test_pdb fails in refleak mode

[Xavier de Gaye]

Xavier de Gaye added the comment:

The doctests are executed with 'test.globs' as globals which is set in the 'find' method of doctest.DocTestFinder, and cleared after each run (unless 'clear_globs' is false).  One possible fix is to have test.regrtest 'find' a new test_runner before each run instead of always using the same one. This is what does the attached patch.
