CS4620/4621 textbook errata

The following errors have been found in the chapters that were handed out for 4620. Pete Shirley also maintains a list of errors for the second edition here.

I will pay a bounty of $1 to the person who first reports each error found in the draft (which implies that if I find it myself and get it on this list before it's reported I get to keep my dollar). To round out the fame-and-fortune package, you'll also get a mention in the preface of the third edition. (There's no need to report errors in formatting or typography, or dangling cross-references, at this stage; just errors in the content.)

I am also looking for clever remarks to put in the margins. Humor, insight, tangential facts, etc. are all welcome.

Positive line numbers count from the top; negative ones count up from the bottom.
