The ones you did look good to me. I would hope that we can do all other
architectures the same way, even if they have special assembly wrappers
for the old clone(). The most interesting cases appear to be ia64, alpha,
m68k and sparc, so it would be good if their maintainers could take a
look.
What do you use for testing? Would it be possible to override the
internal clone() function in glibc with an LD_PRELOAD library
to quickly test one of the other architectures for regressions?
