   …uicide delay to allow users to configure how long they're willing to wait for orderly shutdown

   This will not be useful on Windows, as there is no easy way that I can see for shutting down JVMs cleanly. I dug around for a while and it looks like the JVM devs also haven't found a reasonable way to do orderly shutdowns on Windows https://bugs.openjdk.java.net/browse/JDK-8056139. We can probably be excused for not doing better.
   
   On Linux it works as expected. Tested by running ExclamationTopology with a `cleanup` that sleeps for 15 seconds, and setting the timeout parameter to 30 seconds. The worker was allowed to shut down cleanly.
