 ** \brief An exception signaling that a Theory should immediately
 ** stop performing processing
 **
 ** An exception signaling that a Theory should immediately stop
 ** performing processing and relinquish control to its caller (e.g.,
 ** in a parallel environment).  A Theory might be interrupted if it
 ** calls into its CVC4::theory::OutputChannel, and it should only
 ** catch this exception to perform emergency repair of any invariants
 ** it must re-establish.  Further, if this exception is caught by a
 ** Theory, the Theory should rethrow the same exception (via "throw;"
 ** in the exception block) rather than return, as the Interrupted
 ** instance might contain additional information needed for the
 ** proper management of CVC4 components.
