During review for JDK-8292695, we tried to add a test that checks that under -XX:+ReduceSignalUsage, SIGQUIT should make the process terminate abnormally.

However, this is difficult due to JDK-8234262. Even the workaround of passing -XX:+ReduceSignalUsage to the parent process did not work, probably due to how jtreg launches the parent process with "@run main/othervm -XX:+ReduceSignalUsage". Another possible workaround is to write a shell test instead of using a Java process (ProcessBuilder API) to launch the subprocess. I uploaded the non-working version here: https://github.com/caoman/jdk/commit/73e3a5f90985fcad9a383c704429cefb07011932

It is better to wait for JDK-8234262 to be fixed, then add this test.
