[issue36829] CLI option to make PyErr_WriteUnraisable abort the current process

[STINNER Victor]

STINNER Victor <vstinner at redhat.com> added the comment:

Another example of hook: hook_file.patch logs unraisable exception into ~/unraisable.txt. Patch written for my latest PR 13187 (with the new 'msg' parameter).

Example of output when running the Python test suite (using multiple processes! ./python -m test -j0 -r):

IMHO such hook is more convenient than killing the process with SIGABRT ;-)
