How about exec? Olin Shivers writes:
"Unfortunately, the Unix exec(2) syscall's support for scripts
is not very general or well-designed. It will not handle
multiple arguments; the #! line is usually required to contain
no more than 32 characters; it is not recursive. If these
restrictions are violated, most Unix systems will not provide
accurate error reporting, but either fail silently, or simply
incorrectly implement the desired function. These are the facts
of Unix life".
Are they the facts of GNU life too?
