   > I think this should have tests associated with it. If we are explicitly 
catching and exception and optionally ignoring it there should be tests that 
cover both cases.
   
   I'm going to need some help with writing a test that consistently hits the 
race condition where the `checkExecutor` is shut down and then attempts to 
execute something. I wasn't able to reproduce the failure in 2000 runs of the 
distributed test that originally hit it, and making a unit test for it seems 
extremely difficult as there is very little visibility into the methods that 
would need to be stubbed/modified in order to ensure things happen in the order 
we want.
