Autosaving

Autosaving in MrEd is performed by registering with a single autosaver daemon. Objects that are registered with the autosaver must have a do-autosave method that is called periodically with no arguments.

  (mred:register-autosave obj) 

This registers obj with the autosaver. There is no need to de-register an object because the autosaver keeps a ``weak'' pointer to the object; i.e., the autosaver does not keep an object from garbage collection.
