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