Preventing the script from reading stdin is pretty severe don't you think? Alternatives:
- Open fd 3, pass /proc/self/fd/3 as the script name.
- Pass /proc/self/script as the script name and add code to proc to support this -- this provides the interpreter with fds 0,1 & 2 as the only open ones which it may be expecting.
