<pre>Linux fence FDs are the obvious first implementation choice, and there are some
vendor-extensions to import/export them from EGLSync.
However, given the existance of Vulkan, EGLStreams, and non-Linux systems, it
would be nice if the solution weren't too tied to the semantics of a specific
type of fence object. I'd like a Vulkan app to be able to send a cross-process
Vulkan semaphore of some sort to a Vulkan-based compositor, for example, and
preferably to be able to share it up-front and reference it later, rather than
import/export it every frame.</pre>
