I've not used this, but it isn't necessarily a problem. It sounds as
if you have 100% usage because of something that is accepting idle
messages - annoying as the CPU indicator doesn't really give a useful
result, but non-idle tasks should still be done before whatever is
grabbing the idle messages.

Disclaimer - this is a general impression, and quite possibly wrong.
