I'm not fully convince by the explanation. If you are pushing a buffer on the
srcpad, you'll have to wait for that call to return before you can make any
serialized operation like sending caps event, doing allocation query etc. That
is because the srcpad streaming lock has been taken from another process.

What am I missing ?
