I am facing this same issue on other linux distros. The most I could find about it was in a linux-kernel thread from 2006. At that time the kernel was not designed to support inotify on proc. Hopefully ubuntu can make some progress. There were some proposals for alternate methods in the thread, maybe they can be of help. http://help.lockergnome.com/linux/inotify-proc--ftopict486108.html
