--- Comment #28 from Cy Schubert <cy at FreeBSD.org> ---
Continuing to test on my sandbox (other machines are still busy on other
builds):

ARC: 429M Total, 9067K MFU, 262M MRU, 2618K Anon, 4246K Header, 151M Other
     ^^^^        ^^^^^

buildworld/buildkernel -DNO_CLEAN and tar of /usr/src in progress.

ARC: 445M Total, 3880K MFU, 281M MRU, 2288K Anon, 3056K Header, 156M Other
     ^^^^        ^^^^^

I unset the arbitrary limits kmem_size_max andn kmem_size limits. They are now:

bob<2># sysctl vm.kmem_size    
vm.kmem_size: 5181820928
bob<2># sysctl vm.kmem_size_max
vm.kmem_size_max: 1319413950874
bob<2>#
