If that is true, that I was in the wrong, however if I am
right, then I'll demand yet another apology.

Nope, I compile exactly the same code, for the same target NetBSD
platform, the only difference is running freebsd emulation of
NetBSD for compiling the platform. The compile times compiling
EXACTLY the same code, in EXACTLY the same circumstance, on
EXACTLY the same hardware, for EXACTLY the same NetBSD client.
We are either cross-compiling the target code under NetBSD, or
cross compiling the target code under FreeBSD. Absolutely
no differences in the code being compiled.

I agree, but that isn't what I have been saying. Controlling the
build process NetBSD is much slower, under identical circumstances.
All this means is that NetBSD hasn't addressed some issues that we
have. It doesn't mean that NetBSD isn't lame, but it does mean
that being arrogant about your OS isn't always a smart thing, and
can make you look very very stupid, and owe people apologies.
