You need to serialize that c data struct somehow which you can load when the session 'wakes up' again. I imagine that might not be possible for sockets, so you need to resort to some deamon for that to keep the sockets survive after a request ends. Now there is a solution for this already: SRM.

How I can determine which session is no longer used and can be freed? The garbage collector is called according to your php.ini settings. If you provide a GC from your session handler, you can then close your 'sessions' yourself. > > 3. At the moment my work rests in the cvs tree of our project, and I want > them to stay there.

No, you don't need too, but if you use them they show memory leakage when the script ends, and it might be slightly faster.
