Describe the issue

Chrome tabs freeze when navigating links on Ocsigen.org. The page becomes unresponsive, and the tab takes longer than normal to close.

One or more specific URLs where the issue occurs

http://ocsigen.org/

Steps for anyone to reproduce the issue

1. Visit http://ocsigen.org/.
2. Click the big button that says "Tutorial: Your first app in 5 minutes!"
3. Observed behavior: address bar changes to the target link; page does not update; the mouse pointer remains in the "pointer finger" state everywhere on the page. Fan starts running very high, but I couldn't get the Chrome dev tools profiler to work, presumably because the tab itself wasn't responsive.
4. Middle-click the browser tab to close it; there will be a noticeable lag before the page is able to close.
