Except that is the bacterial model. When you want something done, you signal for it by releasing proteins, and keep releasing proteins until you're satisfied even if the work ended up being done 50 times more than you needed. That's why biological systems so commonly overreact to stimulus. The biological method is to flood communication until whatever demanded response is met. It's the equivalent of a user mashing a button until a program responds, like the elevator button problem.
Actually, elevators seem like an extremely good analogy for this kind of asynchronous service system.
I understand we're not trying to perfectly mimic the analogy, but I think it's important to see that nature's model, while robust and asynchronous, carries significant problems due to how it communicates. It's that very robustness that we're trying to mimic, so we should expect to inherit some of the problems that go along with it.
