async lookup?

[Gary P Cole <Gary.P.Cole@Sun.COM>]

Should a 'lookup' be executed asynchronously?  Or should we state that a 
'lookup' must be synchronous?

The last time we hashed over sync/async, Doron said that any operation 
could be asynchronous unless there was a specific reason to preclude 
async execution.  We've so far established specific reasons why 
'status', 'cancel', and 'listTargets' must be synchronous.
