timeout(sec, klass = nil)
public
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().
