Yeah, though that doesn't explain why "no other application seems to
exhibit such a delay when exiting".  Plenty of other applications ought
to be supporting the clipboard manager spec these days.

There are various possible workarounds, e.g. we could have
x_clipboard_manager_save_frame set x-select-enable-clipboard-manager to
nil if it hits a timeout, so that the delay at least won't recur in the
same session.  But it wouldn't be wise to implement them until we get a
few more details about the actual failure case.
