after extensive testing I found a hardware protection fault + 
mprotect to take 2000nsecs on every hardware I tested, the only 
time you need them active is during a concurrent mark and sweep. 
I'll find out I guess.

Boehm's GC uses this and regularly kept up(~5-10%) with 
essentially all of the top of the line GCs in all the papers I 
read.
