A surface import hit recorded the caller's IOSurface object, which the import never retained. A completion thread then read the retain count of a freed object in pruneHeldImports, and backboardd died on the isa authentication (i35abaf83, twice, at 879 s and 905 s). The table now records the surface the import itself retains. i35abaf83 read 0x6E23 and the framebuffer stayed RGhA. framebuffer_pixel_format also takes RGhA from the device-is-virtualized byte; the render server now reads it back (0x6E30 bit) and notes the key that sets it.
