The current trunk is back to hanging forever in this scenario.  Test
case:

$ emacs -Q

Then select some text with the mouse and then `C-z' in the shell to stop
the Emacs.

Then start a new "emacs -Q" and use mouse-2 to paste.  Emacs will now
hang forever (until you hit C-g).  So it seems like things have possibly
regressed a bit, since it used to heed x-selection-timeout?

Perhaps Po has some insights here; added to the CCs.
