…of forever Some GPU drivers lose a fence's completion signal across a power state transition, wedging the renderer thread (and everything waiting on state->lock) permanently. Track the last vsync and frame period via the shared state, and time out the wait at roughly one frame period instead of EGL_FOREVER.
