Maybe YOU don't feel a need to turn it off for YOUR debugging, but it
is sometimes legitimately helpful to diff two debugging output
transcripts that include pointer addresses to isolate where a
difference happened.  I have often done this.  Any ASLR breaks this.

If these are `changes that were agreed upon' months ago, then you can
cite the agreement from months ago, because it happened on a public
mailing list with a public archive, right?  Then, you can find out
what the nature of the disagreement is:

- Were the changes discussed on the right mailing list or not?
- Did someone misunderstand what the changes you proposed were?
- Did you address all of the issues raised in the thread, or is this
  the same issue as one that was raised before?
- Was this consequence of the proposed changes clear?

Once you have identified that, you can work to find a resolution --
not just call people idiots because they don't share your priorities
about ASLR.

So please try again, maxv.  Your last message was incredibly
disrespectful to other members of the project who have spent decades
with NetBSD doing debugging and diagnostics with tools your changes
broke.
