oneWireHub - is it possible to simulate 2 Hubs?

I am using Teensy3.2 as a simulator of ds18b20. It works fine. However, I need 2 ds18b20s, and not on the same hub ... so I just declare second Hub - hub1 and attach a new sensor to it. In Loop I call the polls for both the hubs.
hub0.poll();
hub1.poll();
Well, it does not work, neither hub0 nor hub1. If I call only 1 poll here, it works well, either hub0 or hub1. What I wonder is, is there a way to simulate 2 hubs? Maybe use interrupt-driven or optimize the poll function?

No. Although you can have multiple objects of that class, the programming is not very cooperative, the blocking parts are wait for longer periods of time, so two instances of this class will not work.
