The point at which it no longer panics from memory exhaustion ;) I've
put no work into finding out exactly where this is, because my servers
have gigabytes of memory and it is a performance optimization for me to
set kmem as high as possible, which was previously just over 1500MB on
amd64 but has now been increased in 8.0.
