Emacs Using 100% CPU

Looks like I will be using EMACS more, again. I am getting sick of waiting for my IDE to "help" me by getting in the way, being slow and hogging lots of memory. I did run into a problem with EMACS hogging the CPU which is fixed by: (custom-set-variables '(semantic-idle-scheduler-idle-time 200)) Emacs Using 100% CPU: "quick fix is to set the Emacs variable semantic-idle-scheduler-idle-time to a large number (by default it is 2 seconds) so that the idle scheduler does not kick in (which is what is using all the CPU)!"
