so in your opinion Nick's mentioning of STREAMS is an insult too? I
certainly do not understand Nick's example as an insult. Is STREAMS now
a dirty word to you that no-one is allowed to use as an example in
kernel maintanance discussions?

Let me recap how I mentioned STREAMS for the first time: it was simply
the best example i could think of when you asked the following question:

(see <20060915231419.GA24731@elte.hu> for the full context. Tellingly,
that point of mine you have left unreplied too.)

btw., you still have not retracted or corrected your false suggestion
that "concessions" or a "compromise" were possible and you did not
retract or correct your false accusation that i "dont want to make
them":

while, as i explained it before, such a concession simply does not exist
- so i am not in the position to "make such a concession". There are
only two choices in essence: either we accept a generic static tracer,
or we reject it.
