I expect the ignored exceptions to be printed into the StringIO object
stderr. With this code there are no warnings on the command line, but
getvalue() returns nothing.
If sys.stderr is not a real file, no error gets printed.
PyErr_WriteUnraisable calls PyFile_WriteString, which checks for
non-file objects and only writes to them when no error is set.
Seems to be a safety measure.
thanks for the quick answer. PyErr_WriteUnraisable calls PyErr_Fetch
first, which should clear the error indicator, and the PyErr_Occurred in
PyFile_WriteString should return false.
