process-queue-interrupt

Arguments: process function &rest args

Like mp:process-interrupt (see that function for a description of the arguments) but calls the interruptions with with-delayed-interrupts being in effect which guarantees order of arrival processing.

Let us say we have three processes, p1, p2, and p3. p2 evaluates

   (mp:process-queue-interrupt p1 #'(lambda ()
     (format t "p2 interrupt processed!~%")))

p3 evaluates

   (mp:process-queue-interrupt p1 #'(lambda ()
     (format t "p3 interrupt processed!~%")))

Then when p1 next runs, it will run those functions in the order in which the interrupts arrived (whatever that is) rather than in a random order.
