// machrunloopserver - C++ shell for writing Mach 3 servers called by CFRunLoop.
//
// Note that this is a subclass of MachServer and tries to preserve its interface,
// so you can switch back-and-forth between them with a minimum of fuss.
// Timers are not currently implemented; they're not that hard to add if you need them.
