It is very unfortunate that neither this nor Linux-kernel performance tests that Yanmin and co tracks has caught these problems much before. Ling Ma's focused tests/analysis for something else started showing these basic issues.

Probably it is best if we can include the very basic checks/tests in the kernel itself. More focused and extensive tests can be done outside the kernel.
