-# = Description
-#
-# A way of performing a potentially long-running operation in a thread, and
-# terminating it's execution if it hasn't finished within fixed amount of
-# time.
-#
-# Previous versions of timeout didn't use a module for namespace. This version
-# provides both Timeout.timeout, and a backwards-compatible #timeout.
-#
-# = Synopsis
-#
-# require 'timeout'
-# status = Timeout::timeout(5) {
-# # Something that should be interrupted if it takes too much time...
-# }

- ##
- # Executes the method's block. If the block execution terminates before +sec+
- # seconds has passed, it returns true. If not, it terminates the execution
- # and raises +exception+ (which defaults to Timeout::Error).
- #
- # Note that this is both a method of module Timeout, so you can 'include
- # Timeout' into your classes so they have a #timeout method, as well as a
- # module method, so you can call it directly as Timeout.timeout().
