Hello, does some body know how to turn off the "stack-sniffer" ?
This device makes it quite complicated/impossible to allocate
heap for temporary stacks in a quasi-parallel system.

  One way to solve the problem could be (if the programming
environment permits it, -- or is well enough documented 
(real programmers doesn't do etc.)) to create an artificial
heap at the stack bottom (or top, depends on your view) and
use this new "heap" for the temporaries of the quasi-parallel
routines :

		  Stack:
		_________
		|	| <- return to finder or what ever
		---------
		|	|
 		.	. <- artificial heap for coroutines
		|	|
		---------
		|	| <- return to clean-up or something
		---------
		|	|
		.	. <- usual stack
		|	|
		---------


		_________
		|	| <- usual heap
			   |
			   V

But it would be niecer to be able to allocate directly from the heap,
especially if you have a unpredictable number of coroutines. Besides
programming it would be niecer !!!
