SHM_ANON is faster and more similar to memfd_create(). Not bothering to
upstream because futex/mksotemp fixes didn't get any feedback after 2 years.
Patchwork is complete crap for one-off contributors i.e., those humble enou=
gh
to not annoy everyone on patch maillist why their contribution wasn't revie=
wed
yet.

libxshmfence is only used by DRI3, so make sure to define LIBGL_DRI3_ENABLE=
 via
environ(7) due to drm-legacy-kmod hacks in mesa-dri and if using
xf86-video-intel add Option "DRI" "3" to xorg.conf.
