btw for async, it is essential that all the scheduled async functions runs as soon as possible;
so make sure that no async work is held back for lack of threads.. just make more immediately.
(the async work is rather latency sensitive, in general it is <poke hardware> <wait a long time> <done>,
the <poke hardware> step needs to be done as soon as possible to cut down the total time; latencies are often
cumulative in async due to dependencies)
