Lion multiuser environment

[Ayrton]

On my 2011 Imac I installed Lion and in a multiuser environment it's super unstable. I experience many, many beachballs and they get worse by not even moving or animating.

Lion is not 100% finished for sure, I went back to SL and then all is ok again. Upgrading to Lion, I will wait for bugfixes to be released before installing Lion again.

Its quite stable here, had big beachballs problems synching contacts with iCloud beta 3. My address book was corrupted and *all* the apps that use it gone completely mad and crash at startup: Mail, FaceTime, address book, system preferences, iPhoto, textedit...just 100% cpu doing nothing and having nothing opened.
solved deleting my address book, don't know if thats the case!
