Re: Deadlock on fragmented memory?

Thanks for doing this.

How difficult you gather it would be to convert the execargs to use 4K pages rathern then continuous KVA, are there any particular gotchas? I would be interested to look at this - it sounds like nice high-kernel only project for me, to make a break from the ATA oddities.

I applied this patch to a netbsd-7 tree (along with the execargs one),
and I have a Xen i386 domU doing a bulk build now. It's still running
pbulk-scan so it's way too soon to see if it helps, but a last the
system boots so it's not worse than before :)
