New posting on MSDN about script leak patterns and how to fix them for anyone that builds dynamic web apps.
Over here on the IE team we take leaks seriously. Extremely seriously. This is contrary to the popular opinion, but I'll let you make your own informed decisions. My new posting on MSDN is specifically designed to help you identify and fix several patterns of leaks. These range from your basic circular reference to your more complex (and more popular) closure based leak. Hopefully this new material can help you identify and exterminate all of the leaks in your code. If you have questions about the article feel free to post here or over on the IE team blog and I'll try to respond to any non-flaming responses ;-)
