When SIGCHLD fires, we may have more than one zombie to be collected. Run waitpid() in a loop until no more zombies are found, and clean them all up. It looks like the SIGCHLD signalfd does not trigger again for remaining zombies, so we need the loop. This works around a crash in text_backend_notified_destroy, which ends up using stale input_method.client if the sigchld handler is not called. The crash could be triggered by removing both weston-desktop-shell and weston-keyboard, so that both would try to respawn and give up, and then quitting Weston.

Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for building weston and its dependencies. The test suite can be invoked via `make check`; see http://wayland.freedesktop.org/testing.html for additional details.
