Hi Trond,

The gr.message(1) isn't to end a packet, it's to tell the scheduler
that there's no more data coming.

I'm not exactly sure I'm following what you are trying to do.
However, I think that if you follow through the logic in
gnuradio-examples/python/digital/tunnel.py you'll see a way to send
and receive packets (fixed or variable length) between python and the
flow graph.
