--- Comment #6 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
as a summary for this task: it turned out to be a massive body of
work far greater than anticipated. the groundwork was laid for
adding 100+ system calls.

mmap support and the beginnings of ELF support combined with enough
system calls were added to run statically-compiled ELF binaries.

future work in bug #1228 is to extend these beginnings further.
a start was made on that work already, and it had to be parked
as it is so large.
