I am in @marak's camp here. You don't want locking. You don't want events
either. Just like you want neither a drill nor a hammer; you want a picture
hanging. Different walls use different tools (drill and anchor for masonry;
hammer and nail for drywall and studs).
What you want is for one task to start when another is complete. In
threads, the solution is locking; in node and an event-driven environment,
the solution is having an event emitter and a callback.
eventEmitter.on("taskdone",function(){
// get started on task B
});
