[issue2604] doctest.DocTestCase fails when run repeatedly

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <amauryfa at gmail.com> added the comment:

FWIW, the python testsuite needs repeatable tests, when running in
"reference leaks" mode.

See also r62100, where a DocTestSuite construction had to be moved into
the repeated function.
