There is another problem with this: the maintainance burden.  People
know ELF, we have ELF and people will know ELF in the future.
Furthermore, as far as I am concerned, GNU/Linux is our main
platform.  I do not mind supporting windows or so and we can support
it in a sane way, but changing our binary formats for it is one step
too far for me...
