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.
