  32  * @brief Simple concrete client request interceptor.
  33  *
  34  * This is a test client request interceptor that verifies that the
  35  * client side PICurrent semantics are correct.  In particular, it
  36  * verifies that the request-scope current (RSC) is not modified after
  37  * the contents of the thread-scope current (TSC) are copied to it.
  38  * This is particularly important for ORBs that initially perform a
  39  * logical copy for performance reasons.
