Test kasync async executor #464
Description
The kasync executor is the centerpiece of multitasking for k23. It needs to be absolutely rock solid. Unfortunately, the testing situation is quite lackluster at the moment and I have experienced a few flaky deadlocks too.
WE NEED BETTER TESTS AND CHECKS!
We need all the help expanding:
- unit test (especially loom & miri)
- fuzzing
- benchmarking
The ideal state of kasync is that we have a solid test suite that all pass under loom.
