An intermediate-to-advanced book on Python concurrency

This is a work in progress. It is being created in the open in order to produce feedback and ultimately make it as accurate as possible.

• The ebook version will remain free, although I haven't yet decided on the specific license.

• This book is written using Pandoc-flavored Markdown. Thus, although you can read the chapters directly in the Chapters subdirectory of this repository, you will see various artifacts from Pandoc's Markdown extensions that don't render via Github Markdown. These are typically minor issues and don't greatly impact readability.

• The epub build system is not yet in place.
