Previously, when popen was called, the 3 streams (stdin, stderr and stdourt) where never closed. This was the reason of the having an impossible number of open files.
This patch ensure all streams are closed after using them. This means that the ulimit trick is no more necessary
- Moved common CPArray/CPSet collection KVC operators to _CPCollectionKVCOperators.
- Implemented KVC operator dispatch using Objective-J.
- Fixed infinite loop with empty collection in @min, @max and @sum operators.
- Correctly return valueForUndefinedKey when necessary.
- valueForUndefinedKey reason uses raw description for consistency, class' overridden description may not helpful at all.
- Don't create a forwarder for @ operators with property paths.
- Fixed CPSet -valueForKeyPath to correctly deal with nil/undefined/empty values.
- Added tests for collection KVC operators.
- enumerator -nextObject should always compare against nil for clarity, correctness, and consistency.
1. Split out flatten specific code to get file size back down.
2. Fix for non-native string URL not working with the URLCache (typeof x !=== "string")
3. Fix for slight IE performance regression.
