We will change the glibc emulation to avoid trying to lchmod symbolic links in this way. This will avoid triggering the kernel bug. (We'd really like to get a proper fchmodat system call with a flags argument, though, for AT_EMPTY_PATH and AT_SYMLINK_NOFOLLOW.) And part of my testing was wrong, this is a symbolic-link-only issue.
