--- Comment #19 from Jonas Ådahl <jadahl at gmail.com> ---
Yes. mesa listens for release events and keeps track of what buffers are in
use. IIRC it'll normally keep 2 or 3 buffers, depending on whether its a
synchronized subsurface or not, in which it needs 3 (active, cached, pending).

Assuming we are not copying the EGL buffer content, in mutter we need to wait
with sending wl_buffer.release until the buffer is replaced by some other on at
least the next commit.

I'm not sure if we'll need to hold the buffer even longer when we have
buffer->plane optimizations.
