Do not start algorithm engines. NOTE this will cause the vast majority of recipes to fail.
Do not create an invocation specific temporary directory for the messaging systems but use whatever directory is the usual default. For ADAM tasks this would mean that ~/adam or $ADAM_USER will be used rather than a private ORAC-DR directory. This should only be used when it is required for ORAC-DR to talk to tasks that were not started by the pipeline and could lead to possible confusion if multiple pipelines are running using this flag.
