If you are concerned about the client application using up resources, it
could be the blob handling generating a number of blobnode storage items.
If you call Unprepare and then Prepare every so often that should keep the
client from using so many resources. I would be interested in looking at a
simple sample that reproduces this memory growth pattern since I thought I
made it reuse memory for blobs rather than accumulate it.
