Now that -rc1 is out, lets talk a bit more about this.  Lucho can you
provide some level of justification of why you went for a sysctl
interface versus something directly accessible within the file system
-- that would seem more on-par with the 9p philosophy.

Perhaps its time for a general cleanup of the debug_level stuff -- it
was always ugly to have it as a global, but there was just no clear
way to have the session structure available everywhere we use it.
