Derek Higgins bdcd03d604 Avoid transcending /proc with find
Find doesn't like listings disappearing while its trying to find them,
in this case if a PID directory disappears while find is running. Using
-xdev prevents find from going into ./proc and as a side effect /dev
will also be avoided which is mounted on boot so not needed either.
