title: Use redux store in web-worker
body: <p>I use web-workers to separate heavy calculations from the main thread. Application's stack consists of <code>react</code> and <code>redux</code>. So <code>web-workers</code> are created as an object in a <code>redux middleware</code> using <code>webpack's</code> <code>worker-loader</code>. Application receives huge messages from the backend with a very high speed and each message is processed by that <code>web-worker</code>. For each messages corresponding action and the whole store are passed to <code>web-worker</code> via <code>postMessage</code>. 
  <code>store</code> contains really huge objects and it is expensive action to pass it on every <code>postMessage</code>.
  Is there any way to import or to pass <code>store</code> once to <code>web-worker</code>?</p>
