How deeply does Go in Action, Second Edition cover blocking?

Demonstrates synchronous ParseURL calls and moves them into goroutines, without detailing blocking internals or synchronization mechanisms.

Blocking

As explained in Go in Action, Second Edition

A blocking I/O operation prevents the calling execution flow from progressing until input or output completes.

A blocking I/O operation holds the calling execution flow until input or output completes. Network and disk waits can leave useful work unperformed, making concurrency valuable when tasks are independent. section 9.1

A practical Go design uses blocking operations as work that can run independently:

Fetch RSS feeds concurrently so waiting on one network request does not prevent other feed retrievals. section 9.1

Concurrent RSS fetching

Define printFeedTitle to call gofeed.ParseURL, then launch it with go for each feed URL. The example uses a timed sleep to keep the process alive while fetching completes.
