Because something like per-test refleak checking is completely useless
when testing pure-python code. More generally, because not everything
that will be useful for the stdlib's test suite will be useful to
every single third-party test suite. It's also an issue of support: I
want the freedom to add functionality to the stdlib's test suite
without worrying about the impact on third-party unittest code.
