Thank you for the explanation. I was not sure how the option effected things and
yes it does matter we have this set correctly.

Options can be set in the $HOME/.rtemstesterrc is via the --user-config option.
Maybe this can be used to control the time out for specific user tests?

Sebastian, are some of the standard testsuite test's failing because of this
setting?
