Some of these tests are running slower since JDK-8376568. Further work is required to reduce/avoid the wait in MountUnmountDisabler::disable_transition_for_one, tracked as JDK-8377312. In the mean-time, we dial down the tests.

This looks OK to me. Would `GetStackTraceALotWithTimedWait` need a simlar change in its test defintion and at:


int iterations = args.length > 0 ? Integer.parseInt(args[0]) : 100_000;
