-this is the pd interface to forth processes / processors.
-in time, it should become the only interface between the processing
-functionality in pdp, and pd objects representing this functionality
-
-example object definitions:
-
-a forth process is a virtual machine operating on a private 
-rotation stack, as found in hp rpn calcs (this is the machine state vector)
-the tick operation leaves the stack size and relative position of
-the elements invariant
-
-this is a very crude and simple framework. it is an experiment to
-see how far this forth thing can be pushed to solve the problem
-of dataflow processing in a simple way, by cutting out the fat.
-yes, chuck moore's ideas are viral..
-
-a forth process has a setup code that will construct an initial stack template
-
-an object definition is a list of
-- list of symbolic input to stack location mappings (first = active)
-- list of symbolic output to stack location mappings
-- stack template init code (bootblock)
-- process code
-
-the stack is the machine memory
- 
-the mapping between pdp's forth processors and pd object
-is handled by pdmaps. these can probably be reused to build other
-object oriented interfaces to the forth processors
-
-*/
-
-
-/* pdp forthprocs support thread processing.
-
-   there is only one stack, which
-   serves as the machine state and input/output storage.
-
-   when processing in thread, the input/output event
-   queue is used, when processing directly pd events
-   are inserted into the stack directly and the queues
-   are bypassed
