Closing ssh session causes 100% cpu usage by naim until killed (freebsd)

> What steps will reproduce the problem?

1. ssh/telnet to a freebsd server
2. start naim
3. close the session without warning
4. ssh back in, fire up top, boom, naim process taking 100% cpu

> What is the expected output? What do you see instead?
Naim to exit.  Naim does not exit and seems to snag all the CPU instead,
probably trying to write to a non-existent session.

naim 0.11.8.3.1

This has followed me through several versions of freebsd, both i386 and amd64.

This is not a problem for me, as i screen naim.  However, several of my
users have the horrible habbit of just clicking the close box on putty, and
not exiting things gracefully.  I've had this bug for years now and
although having a script look for 100% use naims and killing them works,
it's a damn poor workaround.  I keep expecting a fix.  Maybe no one has
reported it yet?

I bet this is related to issues #21.

Also, i just tried 0.11.8.3.2, same problem.  I compile naim directly from 
source
using ./configure and make (which uses gcc).
