In computer science, the event loop, message dispatcher, message loop, message pump, or run loop is a programming construct that waits for and dispatches events or messages in a program.
It works by making a request to some internal or external "event provider" (that generally blocks the request until an event has arrived), and then it calls the relevant event handler ("dispatches the event").
The event-loop may be used in conjunction with a reactor, if the event provider follows the file interface, which can be selected or 'polled' (the Unix system call, not actual polling).
The event loop almost always operates asynchronously with the message originator.
A minimal HTTP server in python. It sends a JSON Hello World for GET requests, and echoes back JSON for POST requests.

// In this case the macro DFAKE_SCOPED_LOCK has to be | |
// used, it checks that if a thread is inside the push/pop then | |
// noone else is still inside the pop/push | |
