>
> 	* clienttypes.el (read-list-enter-read-info): When checking
> 	whether to append texts to an existing read-list item, don't check
> 	that conf-stats are eq. Just check that the conf-nos are the same.
>
> 	* prefetch.el (lyskom-prefetch-read-texts-handler): There was a
> 	race condition here which could cause unread texts never to be
> 	read properly.
>
> 	Provide hash-table-like functions in Emacs 19 and 20:
> 	* reading.el (lyskom-mship-cache-create): Use
> 	lyskom-make-hash-table instead of make-hash-table so compatibility
> 	defun is used when needed.
> 	(lyskom-mship-cache-get): Ditto for gethash.
> 	(lyskom-mship-cache-put): Ditto for puthash.
> 	(lyskom-mship-cache-del): Ditto for remhash.
>
> 	* compatibility.el (make-hash-table): Provide compatibility defun.
> 	(gethash): Ditto.
> 	(puthash): Ditto.
> 	(remhash): Ditto.
