But is it really worth the pain? I'd hate to have to audit the entire
VFS to make sure that it works if another thread changes our
credentials in the middle of a syscall, so we either end up having to
lock the credentials over every VFS syscall, or take a copy of the
credentials and pass it through every VFS internal call that we make.
