I forgot to mention ulatencyd integrates with systemd. doh123 there are times that the foreground bias is a curse. The issue is the left over effect of X11 yes the very old evil it is. Due to X11 being cross platform it never had any controls for applications cpu access. Since cpu access owns the the kernel and is OS dependent. Basically windows and OS X have something like ulatencyd hidden inside them. Linux is a little late to the party doing this.
