For those of you who are debugging in the Linux kernel, you might be
interested to learn of ksplice. We used to it ferret out the fakestat
issues which were fixed in 1.5.54 and 1.4.8pre2.

The basic idea is that you patch your in-core kernel image and then
basically keep running as if nothing happened. So if there's running
state you want to preserve, you're set.

Thanks, incidentally, go to Jeff Arnold and the MIT Student
Information Processing Board for ksplice and its use in tracking these
issues, respectively.
