Sharing a single tmpdir is probably *not* the best idea. What you
really want in this scenario, is sharing the session data (and maybe
VFS). In order to do that, configure a Session Handler that is able to
support this (a Distributed Hashtable or if you can't use that, either
SQL or NoSQL Database). You really shouldn't use filebased sessions in
a load balancing setup. You may need to configure a common

Clearing the session files after $conf[session][max_time] is probably
safe to do. Regarding stuff in the VFS, depends on how you configured
