I had it working a while ago, just not using libc malloc(). AFAIU,
that's just incompatible with unexec() now.
(And it's still slightly but significantly faster building with
unexec() on Linux than building with pdumper, at least in contrived
benchmarks).
So, yes, I'd misunderstood Eli and thought he had objections to this
patch; if he doesn't, we should look into fixing the native-comp parts
and apply it :-)
