Ctrl+d, interactive mode and REPL

Good day, list

Is it possible to make cmucl exit when ctrl+d is pressed in
the REPL,
the same was as many of the UNIX`s interactive tools do?

This might look like a compromise to the UNIX side, as per
the
Unix Haters Handbook, but nevertheless it would be a great
convenience
to have this feature.

There is a constant that controls this and it's set to 10,
so 10 C-d's
are needed to exit.  I once changed it to a defvar and set
it to 1.
Even then it didn't really do what you want.  You have to
press C-d
and return.  That caused cmucl to switch input from
standard-input to
terminal-input.  Another C-d/Return exited cmucl.

Having accidentally exited clisp before, I find it rather
annoying,
especially when my Lisp contained lots of state that I
wasn't ready to
destroy it yet.

That`s for top level frame, yes, but what about inner, debug
frames?

Perhaps it could be made configurable?
