Why is this a patch at all?

What's wrong with something like

    tcpserver 0 25 sh -c "sleep $GREETDELAY; exec qmail-smtpd"

?  If you're worried about the /bin/sh invocation overhead, how about
something like (with appropriate error handling added):

    #include <stdio.h>
    #include <stdlib.h>

    main(int argc,char *argv[])
    {
      int delay;
      sscanf(getenv("GREETDELAY"),"%d",&delay);
      sleep(delay);
      execvp(argv[1],argv + 1);
    }

or a dozen variations on the theme?
