Why do we need another System property?
> TimedBuffer need sleep error detection measured against the expected timeout

> Assignee: Francesco Nigro
> Priority: Minor
>
> The current TimedBuffer implementation evaluate the sleep accuracy measuring
> the error against the elapsed sleep time while the original version was using
> the error related to the overall expected timeout: It would be better due to
> the sleep/parkNanos behaviour to maintain the original evaluation method, but
> using the improved discounted (with the last flush time) sleep time in order
> to not exeeding to delay flushes.
