If it held on to generic data (void * and size), I think it could be
useful to a variety of programs.  I was intrigued by the comments
about the undo/redo code saving the undo information to disk as a
method for crash recovery.

Such code could also drop old information from the end of the queue
(and free it), if the information were older than the last normal save.
