Hi! Recently A. Jesse Jiryu Davis asked at Stackoverflow (http://stackoverflow.com/q/24717027/95735) if there is "a way to force a Python 3 unittest to fail, rather than simply print a warning to stderr, if it causes any ResourceWarning?" Daniel Harding, in the accepted answer, states it's not possible.
Is it really the case? For sake of context, here I believe is the place, where PyErr_WriteUnraisable is being called in this case – http://hg.python.org/cpython/annotate/c0e311e010fc/Modules/socketmodule.c#l3857 -- https://mail.python.org/mailman/listinfo/python-list
