dojo.back does not work when clicking very fast

[tanneman]

Steps to reproduce

• Open test page ​http://download.dojotoolkit.org/release-1.7.3/dojo-release-1.7.3/dojo/tests/back.html
• Click on all links
• Click on the back button repeatedly fast

Expected

• All steps are done until the initial state has been reached

Actual

• After the first (few) steps it seems it cannot keep up and no events are generated anymore. The page remains unchanged. Clicking the back button does not do anything after this (only changing the url).

Note: As a reference www.gmail.com works correctly with very fast backbutton clicking
