Get a bunch of these when running epiphany ( Gnome Web ) from command line:

sid@unstable:~$ epiphany
WaylandCompositor requires eglBindWaylandDisplayWL, eglUnbindWaylandDisplayWL and eglQueryWaylandBuffer.
Nested Wayland compositor could not initialize EGL

I came here while working on tests for https://bugs.webkit.org/show_bug.cgi?id=184845 , where I was seeing these IPC error messages as well (plus ones in the IPC receive side)

I would put the EPIPE check inside an OS(LINUX) guard, as it is clearly
something that is specific to the Linux kernel.

  #if OS(LINUX
      if (errno == ECONNRESET || errno == EPIPE)
  #else
      if (errno == ECONRESET)
  #endif
      {
          // ...
      }

Accidentally cleared the r+ flag, resetting and cq+'ing. Hopefully the scripts Do The Right Thing.
