Suspend itimer while in handler
I’ve also done a couple of other experiments in which fine output time intervals are desired. LAB Number 8 LAB Title Timer Mode Periodic Event (in microseconds)

We can define async-style functions that invoke doSomethingUsefulOne and doSomethingUsefulTwo asynchronously using the async coroutine builder using a GlobalScope reference to opt-out of the structured concurrency. The use-case for async(start = CoroutineStart.LAZY) is a replacement for the standard lazy function in cases when computation of the value involves suspending functions. Note that if we just call await in println without first calling start on individual coroutines, this will lead to sequential behavior, since await starts the coroutine execution and waits for its finish, which is not the intended use-case for laziness. We first start one, then start two, and then await for the individual coroutines to finish. So, here the two coroutines are defined but not executed as in the previous example, but the control is given to the programmer on when exactly to start the execution by calling start.
