There's already the --command-fd command, but it's disabled for now
because it still suffers from some issues. This is in dpkg's TODO
list, and I could just enable it back the first thing in 1.18.0,
targetting experimental, so that it can be tested. I think I remember
at least some of the problems with it, related to at least massive
memory usage due to the non-freeing memory allocator, and might even
have some fixes on some branch. But there might be other issues.

Thanks,
Guillem
