Blocking network APIs in transport engine may block the entire runtime #24

Closed crazyboycjr closed 2 years ago

crazyboycjr commented 2 years ago

Two engines sharing the same runtime may block each other. Such calls are prevalent including get_cq_event, get_cm_event, get_request, and connect. Dedicated mode (each engine dedicates a runtime) does not have this issue, but it is not the final solution.

Fortunately, all of these APIs are associated with an fd, which can be polled with epoll/poll.
