For art 3.00.00, secondary file-reading will be restricted to 1 schedule and 1 thread. This restriction might be relaxed for future versions of art. The complications with secondary file-reading in a multi-threaded context art:

1. needing to ensure thread-safe access to the input source during the opening of any input file
2. needing to synchronize the list of "selected products" to be written to any output file whenever an input file has been opened.

Item #1 is probably already taken care of due to the input source's locking mechanisms that are in place. Item #2 is more difficult and will need to be deferred until another time.
