If you accept my cothreadless scheduler defense (do you?),
gst_element_yield really shouldn't be allowed. Well, you could arrange
for it to longjmp back to some earlier point in the call stack... I
really think, though, that we shouldn't rely on state stored in the
stack between pushes and pulls. Loop functions should just return.
("Process functions" would be a better name.)
ps. I got me internet back. Rock the casbah.
