Invariant Violation: Dispatch.dispatch(...): Cannot dispatch in the middle of a dispatch.(…)

I'm using [this](http://alt.js.org/docs/async) approach for asyncs in my application but always getting this error:

> Invariant Violation: Dispatch.dispatch(...): Cannot dispatch in the middle of a dispatch.(…)

I'm async function like this:

```
if (!this.getInstance().isLoading()) {
this.getInstance().performSearch();
}
```

With setTimeout everything works perfect.

Start with the linked async documentation and the Dispatch.dispatch error, then build a minimal reproduction around the shown performSearch call with and without setTimeout. Done means the async path is understood and the reproduction no longer triggers the dispatch invariant.
