I haven't tested the client, but the server side of your patch appears
to work. I applied it to the CVS head (as of about noon -0800 on 07 Jan
2008), and compiled and ran sshd on a Fedora 8 i386 box. Sending the
TERM signal from my custom client (based on ruby Net::SSH) now appears
to work as expected.

To get it to compile, I did have to modify your patch to add the
following line to misc.c:

#include <signal.h>

Thanks! Looking forward to seeing this in the release version.
