The only exec is an execv() at line 740 of inetd.c, which launches the
program that will service a request. It's done irrespective of wrapping.
So you can save a fork, not an exec. Forks are cheap.

I'm not really opposed to having command-line options for per-case

gain us anything significant. :-)
