> [ 10.000000] (2:HostKiller@Host1) HostKiller turning off host Host2
> [ 10.000000] (1:Dispatcher@Host1) Dispatcher has experienced a host failure exception, so it knows that something went wrong
> [ 10.000000] (1:Dispatcher@Host1) Now it needs to figure out which of the two execs failed by looking at their state
> [ 10.000000] (1:Dispatcher@Host1) Exec on Host1 has state: STARTED
> [ 10.000000] (1:Dispatcher@Host1) Exec on Host2 has state: FAILED
> [ 10.000000] (1:Dispatcher@Host1) Waiting on a FAILED exec raises an exception: 'Cannot wait for a failed exec'
> [ 10.000000] (1:Dispatcher@Host1) Wait for remaining exec, just to be nice
> [ 10.000000] (2:HostKiller@Host1) HostKiller ends
> [ 20.000000] (1:Dispatcher@Host1) Dispatcher ends
