Discovered while testing new desktop stuff around hal and friends.
* Make (no need to install) sysutils/consolekit from pkgsrc.
* Enter into obj directory (might be different, but that's
/usr/obj/pkgsrc/sysutils/consolekit/work/Consolekit-0.3/src in my env)
* Start ./test-vt-monitor in there
* Switch VT's and enjoy that changes are logged (or may be not?)
* Press Ctrl+C
* Enjoy deadlocked system :(
