Send SIGABRT to signal-test-app (#324)

talzag · web-flow · commit 41f2ac1fb954 · 2022-06-28T10:09:04.000-07:00
Thread sanitizer doesn't handle SIGINT properly, and this causes the
signal-test-app to hang when tests are run under TSan. Sending SIGABRT
causes signal-test-app to exit under all circumstances.
