EAP method cleanup

Hello! I have a little problem with developing new EAP method. The problem is with the internal data which are used between subsequent EAP request (handler->opaque). My question is: how free session data when user breaks the session before finish? From my observation free_opaque is called only once when method finishes. But what about non finished sessions (intentionally or not) which should be, after some delay, also removed. Is there any solution for this problem?
