Iterator Priorities question
I assume this is correct..but, just double checking.

From the JavaDocs:

*priority - determines the order in which iterators are applied (system
iterators are always applied first, then user-configured iterators, lowest
priority first)*

So, even if I set a priority of "1" for a user iterator, it will (should?)
come after all system iterators have run on a particular

I noticed that the VersionIterator looks to set a priority of 20 by
default..is there a particular reason as to why it's set there?  Just more
curious than anything.
