-   introduces security problems. I should switch all of this to a sort
-   of execl() or execv() interface/implementation.

-/* Like system(3), but with error messages printed if the fork fails
-   or if the child process dies due to an uncaught signal. Also, the

-   Otherwise, the 8-bit return value of the program ala WEXITSTATUS
