"""If a typechecking profiler is active, e.g. created by
pytypes.set_global_typechecked_profiler(), such a profiler
must be restored whenever a TypeCheckError is caught.
The call must stem from the thread that raised the error.
Otherwise the typechecking profiler is implicitly disabled.
Alternatively one can turn pytypes into warning mode. In that
mode no calls to this function are required (unless one uses
filterwarnings("error") or likewise).
