I'm not quite sure what you're objecting to.  If "program" is an
external programme (but you can call it a program if you want :-)) this
is already handled efficiently because the shell exec's it directly from
the subshell, so there's only a single fork.

Beyond that, there are other possibilities, but none of them stand
out as obviously neater or more efficient, given the facts above.
