Looks like.  However, now I thought my FIXME were little more than a 
precaution.  In fact, right now the only places where c_struct_state can 
be modified are protected by a mutex on connections_mutex; this should 
prevent changing the state of a connection during a connection_next() 
call.  Do you see a thread waiting on 
ldap_pvt_thread_mutex_lock( &connections_mutex ); at connection.c:427 or 
connection.c:514?  If that's the case, we probably need to move 
c->c_conn_state = SLAP_C_INACTIVE; inside the mutex in order to be able 
to safely assert in connection_next().  Is it worth?
