+1 on that.

Even following my 'experiment' from yesterday I'm still working on
'partial' upgrades (quit last night & greeted by 144 more this morning).
When it's complete I still won't know which apps may not be working
correctly until they bork in the middle of some critical moment. While
it's possible that everything _may_ be OK in the end, I don't think that
I'd entirely trust the system.
