[Rivet] Multiple messages with rivet

[Andy Buckley]

This script (from the extension I thought it was going to be a binary!)
looks ok to me. There is likely to be a problem at the generator end,
though: I suggest that you take the rivet part out and try generating
just a few events with agile-runmc and writing their output to stdout,
e.g. "-o -". That should help you to work out where it's going wrong.

By the way, you can make your script a bit more portable by using
/tmp/$USER to specify the fifo location rather than hard-coding your
username into the script... that way we can try to reproduce the problem
if it persists.

Cheers,
Andy
