With all these new features a few new processes have risen, some of which include:
revisiond - the storing manager for the new document revision system (currently only implemented in TextEdit I believe).
mtmfs - Mobile Time Machine file system daemon
mtmd - Mobile Time Machine snapshot daemon
locationd - there's is no man page for this process yet but I'm guessing it's for the new location fetch service (applications can ask for your current location).
talagent - apparently it's a "helper agent for the Transparent App Lifecycle feature." I'm guessing they're referring to the new resume feature.
I've also noticed that when Wake On Lan is turned on and you wake the computer with a magic packet with ssh etc. the computer wakes up but the screen doesn't get turned on. This, in my opinion, is a much better implementation of it (at least for me), since I mostly use the feature when have to check something on the computer at night (and ssh to it) or need to access my computer from work etc.
But I can see how this is undesirable for some people.
