Not sure what you mean with that, but there can be more than one plugin
in the HPI running instance.

Yes.

Only the session object is closed and the session id becomes invalid.

No, currently the infrastructure never does call close on the plugins
(maybe it should). The moment it could call close() is if the daemon
where shutting down. In that case, since the process space entirely is
getting reclaimed, all malloc'ed data structures in the plugins would
get cleaned up automatically anyway.
The only time when close() is called on the plugin is if you use
oHpiHandlerDestroy() on the plugin's instance. This is an exported API
and a OpenHPI specific extension.
