Code Diaries: Real Javascript Multithreading Using iFrames

The aim of this example is to demonstrate how you can achieve a form of real, practical and valuable Javascript Multi-threading using IFRAMEs. We will also have a look at a graph showing the speed increase you can get using a real life widget that uses this kind of multi-threading methodology. This is not about simulating multi-threading using javascript timeouts or some theoretical asynchronous bit of code.
