jest: Updating to Jest 22 causes coverage to run out of memory

Since updating to Jest 22 in https://github.com/facebook/react/pull/11956, all React test runs with coverage fail:

A failure looks like this:

 PASS  packages/react-dom/src/events/__tests__/SelectEventPlugin-test.js
 PASS  packages/react-dom/src/__tests__/ReactDOMOption-test.js (8.546s)
 PASS  packages/react-dom/src/__tests__/ReactMountDestruction-test.js (8.088s)

Not sure if this is a Jest issue but figured it’s worth asking.
