Agreed, but that means I need to revive some of my gnulib work to add
O_CLOEXEC to open(), as well as import pipe2() and other CLOEXEC-support
functions into libvirt, to make it faster on modern kernels.  That can
be set aside for another day (post 0.8.6).

Fair enough.  At any rate, your patch looks fine as is;
