But both of these systems are x86_64 systems.
More exactly, why doesn't x86_64 need execmem? Firefox does
apparently allocate memory that is both executable and writeable on
x86_64 systems too.
Its the JS JIT, pre firefox4 it was only available on i686 starting
with firefox4 it works on x86_64 too.
