Bug#810969: libmutter0g: xclip sometimes causes gnome-shell --wayland to become unresponsive

I have modified the “pass” utility to add additional “echo” statements in order
to pinpoint exactly which call to xclip caused the issue, and sure enough,
it happened again!

The offending call is “xclip -o -selection "clipboard"”, but I still cannot
reproduce the issue reliably.

I managed to stop gnome-shell from hogging resources by switching to another VT
and entering  “echo foo | xclip -in -selection clipboard”, but after switching
back its VT, gnome-shell still wasn't usable (at all). I suspect it's a
different bug specific to VT switching, though, has it has happened before with
the gdm VT.

Since then, I reproduced the issue once again, and running the same command from
a SSH session without doing any VT-switching saved my gnome-shell session!
