I haven't the faintest idea how to gain fine control over threads. In
particular, suppose I have 10 of these "executions" going (lets call them
"steplets") and I want to run each of them for 50 byte-codes, then switch
back to the controlling thread and do lots of bookkeeping (I don't control
the code that the steplets run). I also have a bunch of other processes that
I don't want to take part in this "cycle rationing" but rather run as honest
threads.
