hidden win-errs: Let leaking TCs run till end, then hide
+ Detect code breaking the body of TCs eventually hidden win-errors by raising SkipTest ALAP. + submodule.base.py: import classes from `git.objects` instead of `utils`. + had to ++ ulimit 100->110 for the extra code tested (more leaks :-) + Centralize is_win detection.
