pytester: workaround issue causing spawn to crash or hang In pytester tests, pytest stashes & restores the sys.modules for each test. So if the test imports a new module, it is initialized anew each time. Turns out the readline module isn't multi-init safe, which causes pytester.spawn to crash or hang. So preserve it as a workaround.

Fixed a crash or hang in ``pytester.spawn`` when the ``readline`` module is involved.
