I don't agree with such a kludge: 100 msecs isn't the end of the world for a
distro kernel bootup which takes a lot longer than that typically, and we'd
like to
see the build time sorting implemented as well.
Let's fix this for real intstead of a workaround that is going to decrease
the debuggability of the kernel *significantly*.

No, just no ...
Debug facilities need to be robust, dependable and as simple as possible.
