That function is stored in a session-specific table that maps from GUIDs to functions. Without garbage collection, the functions associated with the GUIDs build up for the duration of a given session. The can be memory intensive. So, we've implemented a mechanism where every 75 seconds (a tunable parameter), the browser does an Ajax call to the server saying "page XXXX" is still live. All GUIDs associated with that page are "kept around." If a GUID hasn't been seen on a page in 10 minutes and is not associated with a Comet component that's still live, then the function is removed from the GUID mapping table and will ultimately be removed from memory by the JVM garbage collector. > We're not using Comet or Lift generated form elements.
