13    * Portable Interceptors Current (also known as <code>PICurrent</code>)
14    * is merely a slot table, the slots of which are used by each service to
15    * transfer their context data between their context and the request's or
16    * reply's service context. Each service which wishes to use PICurrent
17    * reserves a slot or slots at initialization time and uses those slots
18    * during the processing of requests and replies.
19    * <p>
20    * Before an invocation is made, PICurrent is obtained via a call to
21    * <code>ORB.resolve_initial_references( "PICurrent" )</code>. From within
22    * the interception points, the data on PICurrent that has moved from the
23    * thread scope to the request scope is available via the
24    * <code>get_slot</code> operation on the <code>RequestInfo</code> object.
25    * A PICurrent can still be obtained via
26    * <code>resolve_initial_references</code>, but that is the Interceptor's
27    * thread scope PICurrent.
