Nope.  There's a one-line fix to rn that makes this behavior go away.

I don't have the line in front of me, but what you're looking for is an
open(2) call, and what has to change is an O_NDELAY (I think it has to 
be added).  Anyway, I use rn all the time, and have been doing it for
so long I forget when I got it.

If no-one else supplies the exact information, I can do the research
to resurrect the patch.  Send me mail.
