[Amforth] Multithreader with tasks

[pito <pi...@vo...>]

Hi, I've read the .pdf document on the amforth's multitasker and, as
I am a newbie with it, I am overhelmed by a term "task" and its
friends so not easy to follow at least on the first reading.  I
think that cooperative mutlitasker is basically a multithreader,
where we may have many threads, and each thread may contain one or
more tasks. 
So for example:

: run1-demo ( my task - interesting stuff in here ... ) ;
: run2-demo ... ;

$20 $20 0 thread: thread_demo \ create thread, allot tcb + stack
space

: thread-demo-start
thread_demo tcb>tid activate
\ words/tasks after this line are run in the new thread
run1-demo
run2-demo
;

and for example:

: thread-stop ( -- ) pass status ! pause ; \ sleep current thread
: thread-sleep ( tid -- ) pass swap ! ; \ sleep another thread
: thread-awake ( tid -- ) wake swap ! ; \ wake another thread


etc...

What I want to show here is maybe the way how to better structure
the stuff - into "threads" and its "tasks"..
