Er, why?  It seems to me it's a matter of changing these three lines
in PyErr_WriteUnraisable():

-           PyFile_WriteString("Exception ignored in: ", f);
+          PyFile_WriteString("Exception in ", f);
            PyFile_WriteObject(obj, f, 0);
-           PyFile_WriteString("\n", f);
+          PyFile_WriteString(" caught and not propagated:\n", f);

I don't see what makes this technically different from the other
solution, "Cannot propagate exception..."

A bientôt,
