:I think the main reason is Matt couldn't find estd so he just hacked up 
:powerd instead. No idea if the functionality is comparable or which 
:would be a better basis for future improvement.

    It took less than 2 hours to write it, but also I want to implement
    a scheduler integration feature that does not exist in estd at all
    that will allow us to consolidate processes on fewer cpus when the
    load is low.

    Plus, it's kinda like dntpd.  Just because someone somewhere wrote
    something doesn't mean it is going to be the best implementation.
