I managed to figure it out myself. I set the b->pos = b->end during my
"traverse the chain and copy all buffers into one" for each buffer
that I copy. I just assumed that "old buffers" will be thrown away by
nginx as soon as I changed the input chain to the new buffer leaving
the old buffer dangling.

Anyways, thanks for the pointer Maxim. Highly appreciated.
