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