Heh, I was doing my own buffering until I found out about KProcIO...I'm
using that now, its very convenient, I like it.

I actually took a cheap hack way out.  There is a line that is "constant"
that appears a few lines before the prompt.  When that line comes in via
KProcIO, I fire off a QTimer.singleShot() to a slot that "manually" prints
the prompt to the user.  Then when the users answers the prompt and the
prompt text comes in via KProcIO, I just don't echo it.
