Limited Queue based on suggestions from http://stereopsis.com/async/

	# On user event -> push event into a n-element queue.
	# If the number of outstanding requests is <n, fire request immediately.
	# When an outstanding request works or fails, fire a pending queued request if one is waiting.

	EventEmitter = process.EventEmitter or require?('events').EventEmitter or {}

	LimitedQueue = (@n = 2, @log = false) ->
	@log = console.log if @log is true and console? and console.log
	@q = []
	@req = []

Simple shallow copy of global will not work as expected with runInNewContext

	function clone(obj) { var nobj={}, key; for(key in obj) nobj[key]=obj[key]; return nobj; }

	var local = null

	var g = clone(global);

	local = 3
	console.assert(local === 3, 'not initialized to 3')
	console.assert(null == g.local, 'g.local should be null or undefined')

LiveScript: works in a file but not from command-line REPL

	## Looks like functions defined with `->` work but those defined with `function` do not.

	answer = 42
	deepthought = -> "let me think about it for a while"
	function question then answer
