I think there are two things that nedd cleaning up:
1) Clean dead sessions from the DB  to free displays.
2) Clean up hold sessions in the home-dir to free memory.

The first is probably better done as daemon/cron-job. The daemon needs
extended rights, because it needs access to all sessions (this is
relevant due to the postgres-implementation), and needs to run on every
server. Running as x2gouser should do the trick, though.

The second is probably best placed in x2gocreatesession, as the user
should have the rights to clean up it's old sessions (root normally may
not access foreign homes via NFS).

Cheers
