> updateDocument currently attempts to update the document using a String append operation,
and if that fails it will retry with a full rewrite.
> However, these operations may be conditional on the previous value of MODCOUNT. If this
is the case, and the append did not fail with an SQLException, we know that a full rewrite
isn't going to work either, thus we can skip the attempt (thus, the outer retry logic will
need to refetch the document from storage before retrying).
