> The following ideas is to be evaluated:
> 1) "startTime" and "endTime" fields have virtually no value. They are used mostly for
debug and tests.
> 2) "ignoreInterrupts" flag can be encapsulated into state.
> 3) "ArrayListener" concept looks overly complex. Looks like we do not need it at all
-> array can be used directly.
> 4) Modern JDK futures do not use AQS anymore. Instead, they park/unpark directly and
store waiters in a kind of compact stack. Need to think about it.
