I've been using it without any issues. It offers some useful tools once you understand what it does and how it works. It allows you to group processes and partition off how much access they get to different system resources. This is a handy tool for limiting non-audio processes and keeping them under control. Remember, cgroups is for more than just CPU time. It can deal with things like memory, hard drive bandwidth, etc.
Furthermore, unless you mount the cgroups virt filesystem, it shouldn't have any effect at all.
I doubt this has as much as an implication on Gentoo users as it does for pre-packaged distros where the decision of mounting cgroups is not an explicit decision of the user if the distro makes mounting cgroups the default config.
