  14  **
  15  ** An exception signaling that a Theory should immediately stop
  16  ** performing processing and relinquish control to its caller (e.g.,
  17  ** in a parallel environment).  A Theory might be interrupted if it
  18  ** calls into its CVC4::theory::OutputChannel, and it should only
  19  ** catch this exception to perform emergency repair of any invariants
  20  ** it must re-establish.  Further, if this exception is caught by a
  21  ** Theory, the Theory should rethrow the same exception (via "throw;"
  22  ** in the exception block) rather than return, as the Interrupted
  23  ** instance might contain additional information needed for the
  24  ** proper management of CVC4 components.
