+Futures are a convenient way to run a calculation in a new thread, and
+only wait for the result when it's actually needed.
+
+Futures are similar to promises (@pxref{Delayed Evaluation}), in that
+they allow mainline code to continue immediately.  But @code{delay}
+doesn't evaluate at all until forced, whereas @code{future} starts
+immediately in a new thread.
+
address@hidden {syntax} future expr
+Begin evaluating @var{expr} in a new thread, and return a ``future''
+object representing the calculation.

address@hidden {Scheme Procedure} future-ref f
