agreed, it's tough... it takes an expert to find all the bugs. Hal Finney was a great programmer, he taught me to look deep to be more stringent; Sometimes it takes a great teacher with a good heart to instill the depth required to write great code. Good competition like that from Dan Kaminsky, who vetted the code extensively and found several little comments for him to find by Satoshi. Needs a great community willing to work together, to point out our short comings and to help us rise farther than we ever had... we truly are standing on the shoulders of giants.
