If unexec is used on GNU/Linux, Emacs is supposed to switch ASLR off by 
using "setfattr -n user.pax.flags -v er temacs", and if that doesn't 
work by using the personality syscall and then re-execing itself (see 
maybe_disable_address_randomization).

I doubt whether it's worth spending much time debugging the problem, 
since nobody uses unexec on GNU/Linux any more.
