It is?  On amd64, vm.kmem_size (not vm.kmem_size_max) is what has to be

for an even longer amount of time we were being told to increase
vm.kmem_size_max.

It seems the wiki should probably be updated - it still says 8.0 and 9-CURRENT shouldn't require
tuning - http://wiki.freebsd.org/ZFSTuningGuide says:
"FreeBSD 7.2+ has improved kernel memory allocation strategy and no tuning may be necessary on systems with more than 2 GB of RAM."
