martin, i'm going to take a leaf from the great rusty russell's book,
because i was very impressed with the professional way in which he
dealt with someone who posted such immature and out-of-line comments:
he rewrote them in a much more non-hostile manner and then replied to

so, here goes: i'm copying the above few [relevant] paragraphs
below, then rewriting them, here:

martin, hi, thank you for responding.

well... actually, as it turns out, the l4linux and l4ka people have
already done most of the work!!

i believe you may have missed part of my message (it was a bit long, i
admit) and i thank you for the opportunity, that your message presents,
to reiterate this: l4linux _exists_ - last time i checked (some months
ago) it had a port of 2.6.11 to the L4 microkernel.

so, in more ways than one, no i am of course not expecting people to
just take orders from someone as mad as myself :)

i really should reiterate this: i _invite_ people to _consider_ the
direction that processor designs - not just any "off-the-wall"
processor designs but _mainstream_ x86-compatible processor designs -
are likely to take. and they are becoming more and more parallel.

the kinds of questions that the experienced linux kernel
maintainers and developers really need to ask is: can the
present linux kernel design _cope_ with such parallelism?

is there an easier way?

that's mainly why i wished you "good luck" :)


p.s. martin. _don't_ do that again. i don't care who you are:
internet archives are forever and your rudeness will be noted
by google-users and other search-users - long after you are dead.
