After reading papers on pax i just realized that 64 bit has
potentially higher security than 32 bit. address space layout
randomization is much better since there are more bits to randomize.
it supports nx and has better PIC support.
you dont see much benefit with less than 2 gb ram though. the higher
overhead of 64 bit pointers is significant. but i am more than happy
to buy more memory. 4gb nowadays cost as much as 1gb a few months ago.
Lay low and nourish in obscurity
