Hi Juergen,

The "-V" (verbose) command line option is nearly completely redundant

different, while the tracing is more informative.

The current position of trace_io() is a bit annoying in write_messages() because it will only be called once the message has been fully written to the ring. Can we consider adding a trace_*() when we are about to write? (Or maybe queue the message?)

I'll address that in a future patch by making trace_io() a little bit more
flexible. In write_messages() I'm planning to either write a single trace
record in case the message could be sent in one go, or split entries for the
start and the end of writing the message.

In any case, I think it is odd to enable verbose and tracing separately. So with or without:
