The filepending message cursor will only spool to disk with the systemUsage limit is reached, up until that point it will keep messages in memory like the vmpendingMessage cursor.

It is possible to limit the temp store, and then the destination will block on a send. If key here is to understand that the spooling to disk with the file pending message cursor is controlled by the shared systemUsage and not the destination usage.
