Delayed computation

Programming with delayed computation

A delayed computation is a function that will do some computation when called. Because of the delayed nature the computation may be asynchronous so the function takes a callback.

Note: the term "delayed computation" is just a temporary name so we can talk about this idea, I do not recommend using this name as it's a) confusing and b) this concept is hard to name.

How to create flamegraphs from the multilevel benchmark. You need to be running an OS that supports dtrace and the ustack helpers, which is not the case for Mac OS X. I created a joyentcloud smartos instance for getting the output.
git clone git://github.com/juliangruber/multilevel.git
cd multilevel
npm install
# comment out lines 19-25 in bench.js and add underneath: fakeNetwork(1e6, log);
node bench.js &
# make sure no other node process is running now
dtrace -n 'profile-97/execname == "node" && arg1/{@[jstack(150, 8000)] = count(); } tick-60s { exit(0); }' > stacks.out
# kill the node bench.js process

A high resolution timer, set the tick duration (default 1s) and callback to be actioned on each tick - accurate to within ~1-5ms per tick and compensates automatically for drift over time.
var HighResolutionTimer = window.HighResolutionTimer = window.HighResolutionTimer || (function() {
var HighResolutionTimer = function(options) {
this.timer = false;
this.total_ticks = 0;
this.start_time = undefined;
this.current_time = undefined;
