The question is what OSes fail to provide enough random bits these days.
This may just be a sanity-checking step (my sanity, at least; I lived through the great entropy hunt of 1995; http://www.cs.berkeley.edu/~daw/papers/ddj-netscape.html [link courtesy dwagner]).

What would you be waiting for? Ignoring Ecma, just adding code to WebKit doesn't make a cross-browser standard. Never mind Firefox (we'll do something soon enough to match). What about IE?
It seems to me we (whatwg members, w3c members; browser vendors in general) need something more than IDL in the way of a spec.

Ok, that seems fine (now that I have read your patch -- thanks for the link!).
