       Safely execute some blocking code.

       Executes the blocking code in the handler <code>blockingCodeHandler</code> using a thread from the worker pool.

       When the code is complete the handler <code>resultHandler</code> will be called with the result on the original context
       (i.e. on the original event loop of the caller).

       A <code>Future</code> instance is passed into <code>blockingCodeHandler</code>. When the blocking code successfully completes,
       the handler should call the {@link Future#complete} or {@link Future#complete} method, or the {@link Future#fail}
       method if it failed.
       <p>
       In the <code>blockingCodeHandler</code> the current context remains the original context and therefore any task
       scheduled in the <code>blockingCodeHandler</code> will be executed on the this context and not on the worker thread.
