Thanks.  I didn't know about those either.  Is there anything
currently broken with our readline wrapper that needs fixing, though?
If it's working, I would rather leave it alone.  We may in the future
want to really return to the main event loop while we're waiting for
the user to type, so that we can notice target events in async mode.
A blocking call to readline is a problem for that.
