Except, they're not really ELF binaries. ELF doesn't allow you to do
both at the same time in the headers, so this adds a new header and is
essentially an encapsulation for other ELF files. Thus, a kernel patch
is required and it would be some time before all kernels supported it.
I'm not against the notion of this...but I think some of the usual
suspects need to get involved in standardizing such an ELF hack.
(You might be able to do something with binfmt_misc as a hack)
