            Bug ID: 89386
           Summary: weston-launch ends in tight poll/recvmsg loop when

          Priority: medium

[Patch] Also quit(wl) on EOF for wl.sock[0]

When sending SIGTERM to weston-launch to terminate session, or even when weston
fails to start (e.g. no GLESv2 support), weston-launch ends up in tight poll()
& recvmsg() loop where poll() returns POLLIN|POLLHUP for wl.sock[0].

This issue seems to only happen when stracing weston-launch.
