Here is the pull request for introducing and implementing XResource extension v1.2. We decided against sending the patches to avoid spamming the list, but we can send them on request. We have taken into account all the review comments from the list so far. (Thanks for reviewing!)

Version 1.2 provides the ability to determine the real PID of all the clients and the capability to accurately account for the resources used by them. Not all resources yet support calculating their sizes, but support for particular resource types can be added later as required by adding small local changes to register their resource calculation functions with this code.

There never was a real v1.1 of the resource extension due to an accidental release of version 1.1 in the repositories. This is mentioned in the protocol description.

These patches include a generic implementation of hash tables as well, instead of implementing one intertwined with the rest of the code. The implementation isn't particularly optimized, but is suitable for this use and can be further optimized in the future, should the data structure find other, more performance-critical, uses.

Current version of this extension also includes XCB XML description, supported by a variant of the test program. So it turns out it was flexible enough after all :).

The extension has been tested. A tool to help testing can be found from:
