The code is now in linux-2.6.18-rc2 the feature is called per-task delay accounting. It gives me my first set of copyrighted files in the Linux kernel, download -rc2 and open up kernel/taskstats.c, include/linux/taskstats*, Documentation/accounting/getdelays.c
The Documentation/accounting directory has a lot of details on how to use and extend our feature. The review processes was very informative, learning and entertaining.
If you are interested in seeing how the review happened, the process, let me know and I'll post the relevant URL's. In case you are interested in what's happening in the Linux Kernel front, Andrew Morton gave a talk at OSDL Japan, about the new features and their current status.

Awesome!!!
So, the next time I get per-task improved performance, I know whom to blame! :)
Well, we hope the data will be useful for determining bottlenecks and several other places. If things go well, you might see a paper on it sometime in the future.
I have my fingers crossed.
