If the consumer happens to check the EOS flag before it hits the
exception injected by the abort (by calling fill_buffer()), they can
think the stream ended normally and expect it to be valid. However this
is not guaranteed when the reader is aborted. To avoid consumers falsely
thinking the stream ended normally, don't set the EOS flag on abort at
all.
Additionally make sure the producer is aborted too on abort. In theory
this is not needed as they are the one initiating the abort, but better
to be safe then sorry.
