[Bug 380500] [NEW] Defunct Fuser Childs in Cameramonitor

[Zero]

Public bug reported:

Binary package hint: cameramonitor

Ubuntu Jaunty 32-bit Camera Monitor 0.2-2

Camera Monitor spawns "fuser" and the process goes defunct for a little
time, also it keeps respawning new fuser proceses rotating the PIDS more
often.

Solution: Don't use child processes (fuser) for file monitoring, if
possible conduct the test using python internal machinery (I think there
should be one way).

A more elegant solution is to use dbus to notify that the camera is in
use through a signal, thus eliminating the dependence of /dev nodes,
allows to manage multiple video devices and makes it possible to discern
between webcams, camcorders or tuners and capture devices. Also
notification is displayed almost instantly without a grace period.
