http://www.whatwg.org/specs/web-apps/current-work/multipage/timers.html#dom-windowtimers-settimeout 
step 5 (though note also step 9, which is the part that makes 4ms a 
minimum delay, not a hard line).

Also note that the 4ms thing only applies to "nested" timeouts.

P.S.  If one draft spec is preferred over another one, the same text is 
at 
http://dev.w3.org/html5/spec/Overview.html#dom-windowtimers-settimeout 
and at http://www.w3.org/TR/html5/timers.html#dom-windowtimers-settimeout
