Improvements to OML example application.

The example generator got extended with a -q flag to supress any printing
to stdout. Also the -s option was extended to suppress any delays in the

stress tester for the buffered_writer's load shedding algorithm and the
multithreaded nature introduced by the 'buffered_writer'.
