Can a setImmediate() function scheduled in an I/O callback recalculate timeout for other I/O notifications?
问题 There is the poll stage of the Node js's event loop. Its aim is to blockingly wait for I/O notifications and then execute needed callbacks. A timeout time of the waiting is calculated before entering this stage. If there were operations scheduled through setImmediate than the timeout is set at 0, if timers took place than timeout is set with a view of them and if there are no such impediments the blocking would continue "forever". What will happen if the timeout is initially set at "infinity"
