Hi Anthony,

In Listing 4.27, you say that you will rewrite Listing 4.26 which uses std::experimental::barrier to instead use std:: experimental::flex_barrier. In doing this you have ended up changing the behavior of the program.

Listing 4.26 will work if source had just enough data in it to split it once i.e it would still work if source.done() returned true after splitting the data block in it once.

But Listing 4.27 won't work in this case with the threads falling out of the while loop immediately which is a flaw.

Regards
Madhusudhan
