Yea, this is pretty much how X11's clipboard works. In case of pasting I
kinda used to revert to stoppable workspace momentary, so that stopped
application had a chance to transfer things.

I was also thinking of making a delay, say 10 seconds before stopping,
that will cover most cases and might be a nice additional feature by
itself.
