The development of the VM has been _full_ of well-intended,
well-reasoned patches which failed to work properly for subtle
reasons. I despair of us ever getting the 2.4 VM right as long as
people think it's safe to submit VM patches without even basic
performance testing.
This isn't an experimental kernel. It's supposed to be a stable
branch.
Cheers,
Stephen
