    Alternatively you can fork a new process that asynchronously handles calling this service in a loop. In that case you are happy if this call blocks your thread until it needs to take care of something and would call it with a large nonzero timeout. Your loop then takes no CPU while there is nothing happening.

    If you are calling it in a single-threaded app, you don't want it to wait around blocking other things in your loop from happening, so you would call it with a timeout_ms of 0, so it returns immediately if nothing is pending, or as soon as it services whatever was pending.

    Under some conditions connections may need service even though there is no pending network action on them, this is "forced service". For default poll() and libuv / libev, the library takes care of calling this and dealing with it for you. But for external poll() integration, you need access to the apis.

    If anybody needs "forced service", returned timeout is zero. In that case, you can call lws_plat_service_tsi() with a timeout of -1 to only service guys who need forced service.
