Yes.

That said, I *do* have some very dim memory of us having had real
issues with the /proc/<pid>/exe thing and having regressions due to
holding refcounts to executables that were a.out binaries and not
demand-loaded. And people wanting to unmount filesystems despite the
binaries being live.

That said, I suspect that whatever issues we used to have with that
are pretty long gone. I don't think people use non-mmap'ed binaries
any more. So I think we can try it and see. And revert if somebody
actually notices and has problems.
