	I saw this on a very recent stable (thud) as well.

>Description:

	When you logout while a patch is running, and it has to
	ask questions, it will try to do that anyway -- and goes
	into an infinite loop.

>How-To-Repeat:

	% rlogin localhost
	% cat t
	#!/bin/sh
	sleep 5
	patch < /usr/ports/net/zircon/patches/patch-aa > log 2>&1
	% sh ./t & logout
	% ls -s log
	% ls -s log
	% ls -s log
	% ls -s log
	
	and watch it grow forever as it fills up with these two lines:

	File to patch: 
	No file found--skip this patch? [n] 

>Fix:
	
	No idea, I took a look at the source but patch does too many
	funny things with stdio. ;)
