// This file contains the enlistment type for the TransactionContext state machine 
// It isn't really an enlistment in the PPL sense, but it behaves a lot like one.
// 
// This class holds all the state associated with a TransactionContext state machine. 
// That means the actual TransactionContext (when we have one), the queue of
// active CCC w/ context requests, the right fault to send back if we fail, etc.
