Thank you Greg, I can poke around into this, it would be a bit of a
challenge as the descriptor which causes BrokenPipeError does not appear
to be stored within the exception so differentiating it from other
exceptions might be a bit tricky.
I will look into this in the coming weeks.? Any tips on accomplishing
this?? I was thinking of encoding the fd responsible for causing the
error into the exception somehow and then checking to see if it was
stdout, then not reporting on it.
