JavaScript/CoffeeScript equivalent of Ruby Timeout module

What would be the best way to realize the functionality of Ruby Timeout module in JavaScript?

http://www.ruby-doc.org/stdlib-1.9.3/libdoc/timeout/rdoc/Timeout.html

e.g. to cancel (async) requests which take longer to finish than a given time?

EDIT:

To make clear what I want to achieve:

For example if I do a HTTP request in node.js e.g.

http.request(options, callback).end();

And I want to cancel the request if it takes longer than a given timeout. So unbind the callback or everything what is need to make sure the request has no further effect.

If you want to cancel an (to) long running process create a variable that is accessible within the closure (function) you create with setTimeout

someLongRunningHttpRequest = new HttpRequest("point://some/where")

#cancel the request after 5 seconds
setTimeout -> 
    someLongRunningHttpRequest.cancel()
, 5000

obviously you need an object that is "cancable" or you could simple ignore the result?
