Interpreting the transport state transition from Rolling to Stopped as
an EOF certainly makes sense in many situations. But, I recall trying
to do something similar to Olivier, repeatedly stopping and starting a
non-interactive ecasound session. That would be nice to have (as an
option, perhaps).

This raises the question of how to terminate a non-interactive
ecasound. Olivier's suggestion (Ctrl-C) seems OK to me.
