The reason the #! hack has to be in the kernel is that that is the
only way, short of making the Shell a suid program, of allowing
"suid shell scripts."  Please don't flame at me that suid shell scripts
are inherently insecure -- this may be so, or it may not, but the Shell
is not the only program in the world that can act as an interpreter.
