Ah, I see the problem is that the fchmodat syscall doesn't take a flags
argument at all. In that case I don't think this is fixable (given the
race) without a new syscall, and then only fixable for kernels using the
new syscall. (I.e., unless anyone sees a way to avoid the race this
should be SUSPENDED until the kernel is fixed.)
