            Bug ID: 231184
           Summary: Sandbox performance improvements
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2

The Sandbox team suggested a number of improvements to our sandbox:

1. Minimize regex usage
Better to use enumerate individual names than grouping similar names into regexes. This is a performance improvement.

2. Remove duplicate rules

3. Remove 'defined?' checks for the many things that are supported in all WebKit target OSes.

These will simplify the rules, and should provide some launch time improvement.
