The batch process is tricky. When we import a document, it may have any number of external references that need retrieving and resolving. As they are found, they are added to a queue. As the queue is processed, it in turn adds more references branching off the process. Probably growing exponentially for a few rounds. To try and avoid the worst of the scaling problems, we will limit batch sizes to manageable numbers. It is impossible to extimate just how many or how deep the spidering process will go - we just have to aim and go.

If you have a chunky server, good memory and a large timeout, it's probably fine to push this up to 200 or more.
