I'm inclined to ask why.  Do you believe that there is some great improvement
in efficiency, portability, or maintainability of the existing program to be
gained thereby?

If one were writing a whole new program, and all the platforms on which it
would be run were to have good, working support for kernel threads, then
it would be a reasonable idea.  But to reconstruct a program that was not
designed in that manner is asking for problems - and we're nowhere near
through fixing bugs in the existing code.

INN suffers enough from "second system syndrome" without this.
