Description Michael Rennie CLA 2015-02-18 10:07:23 EST 
Consider the following scenario:

1. you are working on the latest Esprima code base or in textView.js. (very large js files)
2. you forgot you turned on the setting 'automatically show content assist'
3. you haphazardly type 'this.' while deep in an Object / function
4. you sit back and wonder why your browser tab seems to have died.

Part of the reason for this is captured in bug 457402. The other part s that for each AST we create (for content assist especially) we also do a full inferencing pass. What we need is to calculate the affected source elements and only re-parse / re-infer those.
