44 /*Setup has two phases:
45 * 1) Semantic layer first calls init_VMS, which creates masterEnv, and puts
46 * the master virt procr into the work-queue, ready for first "call"
47 * 2) Semantic layer then does its own init, which creates the seed virt
48 * procr inside the semantic layer, ready to schedule it when
49 * asked by the first run of the masterLoop.
50 *
51 *This part is bit weird because VMS really wants to be "always there", and
52 * have applications attach and detach.. for now, this VMS is part of
53 * the app, so the VMS system starts up as part of running the app.
54 *
55 *The semantic layer is isolated from the VMS internals by making the
56 * semantic layer do setup to a state that it's ready with its
57 * initial virt procrs, ready to schedule them to slots when the masterLoop
58 * asks. Without this pattern, the semantic layer's setup would
59 * have to modify slots directly to assign the initial virt-procrs, and put
60 * them into the readyToAnimateQ itself, breaking the isolation completely.
61 *
62 *

604 * time to shut down the VMS system. Calling this causes the core loop OS
605 * threads to exit, which unblocks the entry-point function that started up
606 * VMS, and allows it to grab the result and return to the original single-
607 * threaded application.
608 *
609 *The _VMSMasterEnv is needed by this shut down function, so the create-seed-
610 * and-wait function has to free a bunch of stuff after it detects the
611 * threads have all died: the masterEnv, the thread-related locations,
612 * masterVP any AppVPs that might still be allocated and sitting in the
613 * semantic environment, or have been orphaned in the _VMSWorkQ.
614 *
615 *NOTE: the semantic plug-in is expected to use VMS__malloc to get all the
616 * locations it needs, and give ownership to masterVP. Then, they will be
617 * automatically freed.
618 *
619 *In here,create one core-loop shut-down processor for each core loop and put
620 * them all directly into the readyToAnimateQ.
621 *Note, this function can ONLY be called after the semantic environment no
622 * longer cares if AppVPs get animated after the point this is called. In
623 * other words, this can be used as an abort, or else it should only be
624 * called when all AppVPs have finished dissipate requests -- only at that
625 * point is it sure that all results have completed.
