Can we give up :INTERACTIVE I/O for RUN-PROGRAM?

[Robert Goldman]

Interactive I/O is not reliable across implementations, and is also
difficult to test.

Do we really need to support this?  If you, as a programmer, really want
interactive I/O, you should probably write your own wrapper to manage
I/O to the program.  Some enterprising soul could even write a clone of
"expect" for CL.

I'd rather lose the :interactive option, than have it and have it work
unreliably.

So I'm soliciting comments -- particularly from those who think we
should keep it.

It seems like some people also have a means to search Quicklisp to
screen suggestions like this.  I'd also welcome feedback based on
libraries in QL.

thanks,
