Just another addition to the chorus. Accessing OS X file servers seemed to cause the issue. CPU maxes out with a gvfsd-afp process for every folder I connected to via a bookmark. Simply ejecting all of these resulted in all gvfsd-afp processed terminating and the laptop returning to normal. However that is really not helpful as I might be editing a document on that server for some time, or browsing a folder or what have you.
