--- Comment #2 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
Yes, it seems not thread-safe to use the same GstPoll from two different
threads at the same time... although it tries to allow that (see mutex). And
the docs also allow it for ones that are created with gst_poll_new_timer() like
here (but not for others).

They share the same array for the fds, but this array can be changed by each
call at any time, including reallocation.
