-# Timeout long-running blocks
-#
-# == Synopsis
-#
-# require 'timeout'
-# status = Timeout::timeout(5) {
-# # Something that should be interrupted if it takes more than 5 seconds...
-# }
-#
-# == Description
-#
-# Timeout provides a way to auto-terminate a potentially long-running
-# operation if it hasn't finished in a fixed amount of time.
-#
-# Previous versions didn't use a module for namespacing, however
-# #timeout is provided for backwards compatibility. You
-# should prefer Timeout#timeout instead.

- # Perform an operation in a block, raising an error if it takes longer than
- # +sec+ seconds to complete.
- #
- # +sec+:: Number of seconds to wait for the block to terminate. Any number
- # may be used, including Floats to specify fractional seconds. A
- # value of 0 or +nil+ will execute the block without any timeout.
- # +klass+:: Exception Class to raise if the block fails to terminate
- # in +sec+ seconds. Omitting will use the default, Timeout::Error
- #
- # The block will be executed on another thread and will be given one
- # argument: +sec+.
- #
- # Returns the result of the block *if* the block completed before
- # +sec+ seconds, otherwise throws an exception, based on the value of +klass+.
- #
- # Note that this is both a method of module Timeout, so you can <tt>include
- # Timeout</tt> into your classes so they have a #timeout method, as well as
- # a module method, so you can call it directly as Timeout.timeout().
