The preroll lock is always taken while buffers/events are processed, the
regression here most probably is this:

    gst-launch: add a sync bus handler and move state-change logging there

    The sync handler is called for all mesages, the event loop we previously
use
    was not. In the sync handler trigger pipeline dot dumps and call access for 
    file in tmp-dir to add markers interceptable by strace and co.


Before it would be deferred to the main loop while now it happens from the
streaming thread, giving a deadlock.

Stefan, what exactly is the reason not to use a bus handler on the mainloop?
