DO NOT MERGE - Direct runner debugging
R: @tgroh
1. Converting all the executor services seems to have done the trick on the
60s delay. We should always uses the ones that take `ThreadPoolBuilders`! (Or
actually implement the "one shared executor" task).
2. Added a bunch of debugging logs, finding many seconds of slowly removing
timers. Maybe that's useful information?
