 * Revision 1.1  2001/06/08 23:29:10  bart
 * major refining
 *
 * Revision 1.4  2001/06/07 00:41:49  bart
 * removed a stupid printk line
 *
 * Revision 1.3  2001/06/04 02:14:02  bart
 * merged forward/reverse into one call 'process' which is a function pointer
 * to a specific processor decided in create_context (i.e. con_init)
 *
 * Revision 1.2  2001/06/03 15:23:02  bart
 * fixed ref count bug with context
 *
 * Revision 1.1  2001/06/03 13:17:20  bart
 * added testing facilities
