Suggested change

	@fiber_timeouts[fiber].delete(timeout)
	@fiber_timeouts.delete(fiber) if @fiber_timeouts[fiber].empty?
	timeouts = @fiber_timeouts[fiber].delete(timeout)
	@fiber_timeouts.delete(fiber) if timeouts.empty?

this won't work, the structure is following

{
  fiber_1: { 
    timeout_1: { ... },
    timeout_2: { ... },
  },
  fiber_2: {
    timeout_3: { ... },
    timeout_4: { ... },
  }
}

@fiber_timeouts[fiber].delete(timeout) deletes fiber_1.timeout_1 key therefore it returns what was in the deleted key, whereas we need to check here whether something still present under fiber_1 key
