I've spotted a few more minor typos for the errata list.
p178 - In the middle of the box, the italicised 'eggs' should just be 'egg'.
p208 - 5th line, 'this function that takes an Object' should have 'that' removed.
p334 - halfway down, my old English teacher wouldn't like 'requests the current thread
of execution rest'. It could be either 'requests that the current thread of execution rest' or 'requests the current thread of execution to rest'. I'm English, and American English grammar may not be as strict so you could disagree on this one.
p358 - near the bottom 'in own custom implementation'? Should this be 'in our own custom implementations'?
p358 - same sentence as above. 'forgot' is a tense change within the sentence, which my English teacher also wouldn't like, so 'forget' would be better.
p373 - last sentence - 'Recall that' should be 'Recall that the'.
p377 - First sentence in box - 'a parallel' should just be 'parallel'.
p551 - Q9. 'and as the code would not compile'. I think the 'as' is superfluous here, or maybe it should be 'so'.
