61 * Locking the parent should always be done before locking the
62 * pad-monitor to prevent deadlocks in case another monitor from
63 * another pad on the same element starts an operation that also
64 * requires locking itself and some other monitors from internally
68 * An element has a sink and a src pad. Some test starts running at sinkpad
69 * and it locks the parent, and then it locks itself. In case it needs to get
70 * some information from the srcpad, it is able to lock the srcpad and get it
71 * because the srcpad should never lock itself before locking the parent (which
72 * it won't be able as sinkpad already locked it).
74 * As a side one, it is possible that srcpad locks itself without locking the
75 * parent in case it wants to do a check that won't need to use other internally
76 * linked pads (sinkpad). But in this case it might lock and unlock freely without
