Description

Introduce an EventLoop interface that event management systems such as libev and libevent can implement.

Something like:

EventLoop.hpp

// The interface that must be implemented by an event management
// system. This is a class to cleanly isolate the interface and so
// that in the future we can support multiple implementations.
class EventLoop
{
public:
  // Initializes the event loop.
  static void initialize();

  // Invoke the specified function in the event loop after the
  // specified duration.
  static void delay(double duration, void(*function)(void));

  // Returns the current time w.r.t. the event loop.
  static double time();

  // Runs the event loop.
  static void *run(void*);
};
