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.
