89 * An element has a sink and a src pad. Some test starts running at sinkpad
90 * and it locks the parent, and then it locks itself. In case it needs to get
91 * some information from the srcpad, it is able to lock the srcpad and get it
92 * because the srcpad should never lock itself before locking the parent (which
93 * it won't be able as sinkpad already locked it).
95 * As a side one, it is possible that srcpad locks itself without locking the
96 * parent in case it wants to do a check that won't need to use other internally
97 * linked pads (sinkpad). But in this case it might lock and unlock freely without
