"JS has only made partial progress to catch up to UIKit" in UIExplorer app

[marshallbrekka]

When clicking/tapping rapidly on the back button in the NavigatorIOS example it triggers the mentioned error message.
The comment where that error originates from indicates its probably a bug with the JS, but doesn't indicate what the solution would be.

react-native/React/Views/RCTNavigator.m

Lines 487 to 495 in 1dba7e0

	// We can actually recover from this situation, but it would be nice to know
	// when this error happens. This simply means that JS hasn't caught up to a
	// back navigation before progressing. It's likely a bug in the JS code that
	// catches up/schedules navigations.
	if (!(jsGettingAhead ||
	jsCatchingUp ||
	jsMakingNoProgressButNeedsToCatchUp ||
	jsMakingNoProgressAndDoesntNeedTo)) {
	RCTLogError(@"JS has only made partial progress to catch up to UIKit");

For what its worth the same bug is present in this app as well https://github.com/iSimar/HackerNews-React-Native
