Merge python#28
28: test clean final r=ltratt a=nanjekyejoannah This PR does the final cleanups to address the following: - Allow higher recursion limit for some tests - skip some tests that require very high recursion limits, I used the allowed limit by convention for the first item above - call reset to allow warning propagation in some tests Note: Existing py3k tests fail with a segfault with -3 flag if not run individually, deleting this context manager in over 300 files will take forever, lets only run `test_py3kwarn` and the rest should be tested locally if modified. It took me long to know the source of this segfault, I have solved any issues with new context manager I introduce. If this PR is merged, we can modify the CI, I am going back to implementing the warnings now. Co-authored-by: Joannah Nanjekye <jnanjeky@unb.ca>
