I've added code (it's in review board right now) that will automatically
farm any snippet with the "do:lazy='true'" attribute set.

So, <lift:foo/> will execute the foo snippet inline.

<lift:foo do:lazy="true"/> will execute the foo snippet in parallel and join
the result back to page before its rendered.

This should allow for the use case of going out to ad servers, etc. in
