Is there something like this:

    (try-this-for SECONDS BODY)

If BODY hasn't completed after SECONDS,
everything will be aborted, i.e.
the equivalence of `keyboard-quit' (or whatever

But what has already happened until the point
of abortion don't have to be rolled back or any
state restored or dumped or anything like that.

If BODY do complete before SECONDS it should be
transparent in the sense that what should be
returned is the final evaluation of BODY.
