code: public final Mono<T> take(Duration duration, Scheduler timer) {
  		return takeUntilOther(Mono.delay(duration, timer));
  	}
docs: Give this Mono a chance to resolve within a specified time frame but complete if it
  doesn't. This works a bit like {@link #timeout(Duration)} except that the resulting
  {@link Mono} completes rather than errors when the timer expires.

  The timeframe is evaluated using the provided {@link Scheduler}.
  
  @param duration the maximum duration to wait for the source Mono to resolve.
  @param timer the {@link Scheduler} on which to measure the duration.
  
  @return a new {@link Mono} that will propagate the signals from the source unless
  no signal is received for {@code duration}, in which case it completes.
