GetValue() public method

Retrieve the cell's value, waiting for the given timeout if no value is immediately available.

If a value is present in the cell at the time the call is made, the call will return immediately. Otherwise, the calling thread blocks until either a value appears, or operation times out.

If no value was available before the timeout, an exception is thrown.
