Abstract
There is a disclosed a multi-processing arrangement in which processes running on one processor may utilize processes, called stub processes, running on other processors. One problem that occurs with respect to such a system is that signals, which indicate the occurrence of external asynchronous events, must be processed in a specified order if the system is to work properly. Disclosed is a system for insuring the proper processing of such signals by requiring all such signals to be routed from a receiving process on a adjunct processor to the main user process on the originating processor. Also disclosed is an arrangement for insuring that signals are not lost and that duplicate signals are not processed.
