Answer from @facontidavide : Since the concept of ticking a tree is basically "polling", we don't want to consume 100% of the cpu, bombarding an asynchronous action with ticks. The smart thing we do is that the proposed sleep is actually a std::condition_variable in disguise. So, contrariwise to a regular sleep, it can be interrupted if a wake up signal is sent |

And in which cases a wake up signal is sent? Moreover, what could actually happen by shortening the sleep period? |
