Hi Lou, the sleep instruction effectively shuts down the CPU until the next interrupt occurs. Thus, the idle process conserves battery power if no task wishes to run. I consider this a worthwile feature. If you can do this without a dedicated idle (...) (26 years ago, 8-Mar-99, to lugnet.robotics.rcx.legos)

I am reworking parts of the task scheduler in tm.c, tm.h, et al. I notice, reading the code, that there is an idle process which runs all of the time. There is a note in tm.c; "execi needs pd_idle".
