Procobj bug; -i problem

[Olin Shivers <shivers@lambda.ai.mit.edu>]

I have been waiting for about two years for that -i issue to come back
and bite me. It's annoying, but easy to deal with: just wrap double-quotes
around the -i: "-i". I have contemplated hacking the syntax to make +i and
-i symbols, but haven't reached a firm conclusion.

The missing-procobj bug is a show-stopper. Unfortunately, I can't make it
happen on my Linux and FreeBSD systems. I will try on a Solaris box. I'm
guessing it's an interaction between the GC and interrupt handlers. Ech.
