(future-call f)

Takes a function of no args and yields a future object that will
invoke the function in another thread, and will cache the result and
return it on all subsequent calls to deref/@. If the computation has
not yet finished, calls to deref/@ will block, unless the variant
of deref with timeout is used. See also - realized?.

                ;; future-call is used to implement 'future'.  See examples for 'future'
;; for discussion of an undesirable 1-minute wait that can occur before
;; your standalone Clojure program exits if you do not use shutdown-agents.
