yes i did that. and have restarted and restored a few times. i still get the mysterious temporary freezes. i've read the Apple forums discussions, my impression is that all of the "fixes" reported by endusers (except rolling back to 3.3) are just lucky happenstance and/or the person in question didn't test it long enough afterward so was still in honeymoon period. thanks for suggestion though! (we should def not continue this thread since off-topic)
