The default thread pool does the right thing but we don't have a 
solution for the case where the user/application provides the 
ExecutorService. A possible hack is to specifically handle the 
ThreadPoolExecutor case and invoke its setKeepAliveTime to disable 
trimming back of the thread pool. That doesn't solve the issue 
completely though as it is possible for a completion handler to 
terminate due to an uncaught error or runtime exception. For that case 
the thread is allowed to terminate (ensures the uncaught exception 
handler is invoked, etc.) but it sets us up for potential side effects. 
It has not been a problem to date and clearly this scenario is the 
result of a bug somewhere.
