That sounds right to me.

Great question! Sheesh... I'm running out of ideas as to what the cause
could be. 

Have you tried making note of the exact times you log in/out/restart and
looking at the console and system logs for entries with those time
stamps to see if you might get a clue as to some error condition that
might be at play?

That would be a good test. If it passes, you conceivably migrate your
data from your old account to a new account to (hopefully) rid yourself
of whatever is causing the problem.
