test-nointerrupt: make "sure" the handler "might" trigger (issue6558)
We are sure that the signal got sent in the right time frame, however, we still
have race, so either the code is actually buggy or we need some security to make
sure the signal get processed.
We might be affected by https://bugs.python.org/issue43406 ?
