He also said he knew it was broken on a bunch of architectures. It's a
bad practice to check in code you _know_ is broken, especially when
there's no rush.

Doesn't compile on ARM. Andrew knew it wouldn't compile on ARM when he
checked it in. No ETA on when it'll even compile on ARM.

One of the things that we used to sell NetBSD to our management is
that we believed that one of the advantages of having our code in the
CVS tree would be that we could count on fundamental functionality not
being broken without the community fixing the code. This fiasco with
m:n threads has proven that not to be true and is causing us to
seriously reevaluate the risk involved in using NetBSD.
But in answer to your question, had we been asked, we might even have
fixed SA in general.

No. The unfortunate thing is that someone thought there was an
artificial for rushing this code into the tree. Andrew claimed in his
email that the fixes for the missing architectures were in the
pipe. Knowing that, there was no reason to jump the gun.
We're not talking about functionality that couldn't wait for a few
weeks to get into current.

As far as I can tell, he's washed his hands of solving the problems he
introduced into libpthread. He's written an email saying that his
changes "couldn't possibly" have caused a particular problem and he
_still_ hasn't gotten back to me on the patch I sent him weeks ago.
As far as I know, he's not picked up the slack on ARM, although I
understand someone else has, after we complained.
As far as I know, he's not picked up the slack on restoring M:N
uniprocessor threading, which we use heavily.

Dear world, despite the complete lack of participation by the port
maintainer, EVBARM is an _active_ port. Please to not be breaking it
gratuitously in the future. Kthx.
I want to make something perfectly clear. Several people have
indicated that I'm only complaining out of selfish commercial
interest. That's about as far from the truth as possible. Had my only
interest been commercial, I would have simply grabbed a NetBSD
snapshot and not contributed anything back.
We went to a lot of internal hassle to even get permission to
contribute. We had to justify the expenditure of resources on the
extra overhead of keeping in sync. We worked hard to push an new
architecture port out. We have done everything we could to work with
In return, port maintainers haven't responded, patches haven't been
applied, long periods have passed without any response to queries
about status, and now code that breaks our world is dropped knowingly
broken into -current.
My _commercial_ interest at this point would be to stick with the
snapshot we've got, withdraw the OMAP port, and not bother to send any
more bug fixes.
