This was sent by a New Relic account executive to one of my co-workers as a
follow-up to the trial. Generally speaking, it's a good idea to not patronise
your potential customers. There's no room for more than a single dot in a
business e-mail. Use a spell-checker for your e-mails if you can't spell. Write
in clear English. What do you think?

Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:
