Yes really, although it's not pretty.

On bad rio days (I have them more than most people, I suspect,
although still not very often) I need to debug rio after it's crashed.
If you have a shell prompt, you're golden but it takes a little work.
Hit carriage return until every one gets you a shell prompt; that
means the rio process holding the keyboard open has filled its
buffer.  Then, although echo will still be off, the shell is all yours.
Type
	kill rio|rc
and you'll get echo back and you can restart rio or whatever else
you want to do.

There, isn't that disgusting?  But I helped track down a corrupt
network interface on an IRIX machine a little while ago so I'm in
a debugging, sharing mood.
