Scheduler threads can suspend themselves (i.e. effectively
pretend as if they don't exist)
A scheduler thread can only suspend itself if its actor queue
is empty and it has no actors in it's mute map and it would
normally send a block message
Only one scheduler thread can suspend or resume at a time (the
largest one running or the smallest one suspended respectively)
We can never skip a scheduler thread and suspend or wake up a
scheduler thread out of order (i.e. thread 6 is active, but
thread 5 gets suspended or thread 5 is suspended but thread 6
gets resumed)
