Thanks, Jason.

I bring this up because of this comment --

"*Warning* BlockingConnection is provided for legacy and learning purposes
only and it is not recommended that you use it for a production

The latest git documentation also still has this warning (

"adapters.blocking_connection.BlockingConnection: Enables blocking,

  synchronous operation on top of library for simple uses. This is not
  recommended and is included for legacy reasons only."

So my question is, why isn't this recommended for production use?
