I have tested the patch submitted by Dave Tyson for x11/xfce4-terminal
http://mail-index.netbsd.org/pkgsrc-users/2012/12/20/msg017513.html
"xfce4-terminal uses 100% CPU"
on both DragonFly 3.3-DEVELOPMENT i386 and x86_64, and this patch
corrects the near 100% cpu usage observed when using Terminal(s) in
xfce4.
Please include this patch in upcoming pkgsrc-2012Q4 and possibly
backport to pkgsrc-2012Q3. It is the difference between usable xfce4
on at least DragonFly, and according to Dave Tyson, NetBSD 6 as well.
The source is DragonFly master through
