/dev/tty not available in inferior lisp

Hi,
I noticed that /dev/tty is not available from any inferior lisp when
running in emacs21.3.50.3 (recent, from cvs). This produces problems
when using the LDB on sbcl, which insists on opening /dev/tty for I/O.

from cmucl:

* (ext:run-program "/bin/sh" '("-c" "echo >/dev/tty") :output t)
/bin/sh: line 1: /dev/tty: No such device or address

from sbcl:

*  (sb-ext:run-program "/bin/sh" '("-c" "echo >/dev/tty") :output t)
/bin/sh: line 1: /dev/tty: No such device or address

This only happens in ilisp. I can comint-run sbcl and cmucl, without
anything like that happening.

,----[ M-x comint-run RET ~/bin/sbcl RET ]
| * (sb-ext:run-program "/bin/sh" '("-c" "echo >/dev/tty") :output t)
| 
| 
| #<SB-IMPL::PROCESS 9496 :EXITED>
`----

What's happening there?
