Hi Dave.

maybe this thread is helpfull:
http://groups.google.com/group/comp.lang.forth/browse_thread/thread/ 
8045e6b5d1043043/8e1084d416820324?lnk=gst&q=ISR#

(Search comp.lang.forth for "ISR" - find Elizabeth D. Rather, 26 Jan.  
2005, 20:47; "multitasker question": provide multitasker to do  
interrupt service routines.)

The essence is:
"In the main multitasker loop, if it goes around fully once with no  
task active, it sets low power mode.  This only takes one  
instruction, so it's done in the code of the multitasker loop itself,  
not in any task.  The assumption is that an event will generate an  
interrupt which will wake up the device and then awaken the task  
responsible for the interrupting device."
