Latest update... I was running through a large number of keyword url
updates (16k), uploading the changes in batches of 1000. When running
the updates this way, I was seeing a significant number of
ConcurrentModification exceptions, and no partial failures. I decided
to try a smaller batch size of 200. With the smaller batch size I
started seeing partial failures and then could identify the error - in
this particular case the error that was being masked was a
DistinctError.

So it is interesting that the batch size changes the error that I
receive, and it has me wondering what is the optimal batch size to use
for updates? for creates?
