[demos] Module loading locks up browser

[guest]

Steps to recreate the problem: 1.) Open http://dojotoolkit.org/demos/email-using-0-9 and cnn.com in two tabs. 2.) Reload both tabs. 3.) Try switching btwn tabs while the Dojo demo is loading.

On FF 2, you won’t be able to switch tabs until Dojo is done loading modules presumably b/c the browser is locked. In IE7, you will get an unspecified error on Line 20 when you try to switch tabs.

Again this works smoothly in FF 3 and Opera 9.5

As a note, this is a reproducable bug first mentioned at Ajaxian; not sure what can be done about it but since it's reproducable, I asked the poster (first name Les) to file.

This can be fixed if the email demo uses a custom build, or uses an xdomain/CDN build instead of loading the source from archive.dojotoolkit.org. I can appreciate it makes it hard to get the "latest" code out on the demo, but we probably want a code snapshot for anything referenced on the web site.

nothing to fix here? solution is to use layers and builds, and there is lots of optimization talk in various blogs and books to cover fixing this.
