Briefly, this is somewhat like 'xload' for those familiar with the
X Window System, but with Amiga specific features. The program is
divided into two components: a 'virtual' device that monitors the
use of the CPU (really the ready queue length), the Blitter, and
memory, and the 'amyload' program which graphically displays this
information.
While I'm here, I might as well ask a couple of questions:
1) Why is there an 'added' state for tasks? Why isn't a created
task in the 'ready' state? This burned me once
when I was expecting a newly created task to preempt its
lower priority creator.
2) When a SIMPLE_REFRESH window is moved without exposing previously
obscured areas of the window, why doesn't Intuition simply copy
the rectangular area to the new location, instead of sending
REFRESHWINDOW events to the application?
Thanks, and enjoy!
