SetXid bits on scripts

SetXid scripts are a *bad* idea.

Ability to add additional 'commandline' args, such as
          notlinux$ head -1 thescript
          #/bin/sh

          notlinux$ ls -la thescript
          -rwsr-xr-x   1 root     web         5012 Apr 19  4:43 thescript

          notlinux$ thescript -i
          $ id
          uid=1010(bri) gid=1010(bri) euid=0(root) groups=1010(bri)

SetXid scripts are run without setXid perms on Linux.
Can run scripts with setXid perms using compiled wrapper programs
Can run Perl scripts with setXid perms using suidperl
