16. #### def get(timeout: Long): Option[A]

    Waits for this SyncVar to become defined at least for `timeout` milliseconds (possibly more), and gets its value.

    Waits for this SyncVar to become defined at least for `timeout` milliseconds (possibly more), and gets its value.

    timeout

      the amount of milliseconds to wait, 0 means forever

    returns

      `None` if variable is undefined after `timeout`, `Some(value)` otherwise
