BTW, a few years ago, I presented my clever solution to the double checked 
locking bug to Scott Meyers. I was very proud of it. Scott handed me my @ss (in 
a nice way), but I got my comeuppance.

It reminded me of the hours I spent in high school determined to show that I 
could trisect an angle with a compass and a straightedge. There was always some 
tiny flaw :-)
