Pretty much any program is not all programs. It is possible for a C
program to run without the stdio promise, if it purely operates on
shared memory and just calls _exit(2) when it wants to exit, as
specified in the man page.
It is impossible for a ruby program to run without stdio, there are
various things ruby does internally that require stdio.
Also, good ruby APIs would not require you to explicity specify
something that is always implicitly required. Ruby is not C.
Thanks,
