Ohh, I absolutely see why you have chosen this way for your particular
usecase. I am just arguing that this would rather be more generic to be
merged. If there is absolutely no other way around we can consider it
but right now I do not see that all other options have been considered
properly. Especially when the fd based approach is basically wrong for
almost anybody else.
