The only suggestion i can give is to declare strong guarantees on the
simplest API calls.
For example, let gst_element_release_pad(),  gst_pad_unlink(),
gst_element_unlink() guarantee that no state corruption or deadlock is
possible, from whatever thread is it called. I think this is more
possible to implement using recursive mutexes, which seem to be not
used in gstreamer currently.
Revising functionality guarantees requires revising all the code, but
i think it is worthwhile.
