For things like an occur or grep buffer, I don't think it is necessary
to keep the actual contents around.  They can be regenerated from
scratch fast enough, so just keeping the history and possibly a somewhat
robust cursor location should be enough.  It becomes trickier with stuff
like grep-find which may run for a while.  Still, having the command
history to some depth available conveniently is cheap and useful,
certainly much cheaper than keeping the buffers.
