// CMmDataCallTsy::CancelService

// CancelService is called by the ETel server when it is "cleaning-up" any 

// still outstanding asynchronous requests before closing a client's 

// sub-session. This will happen if a client closes its R-class handle without 

// cancelling outstanding asynchronous requests. Only Mobile API requests are 

// handled here.

// (other items were commented in a header).
