According to the log this wasn't a hot reload but a hot restart.

@jason-simmons This seems like a hang in the shell?
apwilson commentedon Jan 11, 2017
Yeah looks like everything just locks up - hot reload may just be a symptom of that.

After discussing with @apwilson - The engine thread hangs while processing a drag. So far nothing related to hot reload / restart.

Reproduced this and traced it to a call to SkRTree::CountNodes() that never exits. This happened because we created a Skia canvas with a paint bounds rectangle having NaN dimensions.
Do not paint a RenderFittedBox with an empty size (#7489)
Check if the canvas bounds rect contains infinite or NaN values
