shm interface problems

[Aleix Conchillo Flaqué]

This might not be related to your problem, but we also ran into
segfaults due to a couple of shmpipe bugs during last year. I don't
know if you have an updated shmpipe version.

https://bugzilla.gnome.org/show_bug.cgi?id=679385

If I remember correclty, both bugs involved more than one client (shmsrc).
