priorities and idle watchers may need far too much overhead. In such cases you'd set all of the significant priority things in a single loop and all the rest in the second one particular,

"ev_async" - ways to awaken an occasion loop Normally, You can't use an "ev_run" from numerous threads or other asynchronous sources for example sign handlers (rather than various occasion

preferable to prevent the true watcher before starting the idle watcher, so the kernel is not going to must procedure the function in the event the actual processing will probably be
