ConditionVariable objects augment class Mutex. Using condition variables, it is possible to suspend while in the middle of a critical section until a resource becomes available.

Example:

      require 'thread'

      mutex = Mutex.new
      resource = ConditionVariable.new

      a = Thread.new {
        mutex.synchronize {
          # Thread 'a' now needs the resource
          resource.wait(mutex)
          # 'a' can now have the resource
        }
      }

      b = Thread.new {
        mutex.synchronize {
          # Thread 'b' has finished using the resource
          resource.signal
        }
      }
