 Status: Pending => Rejected

default for orphan was 3 in Zope 2.4.X and is now 0 in Zope 2.5.0
(DT_In.py).

Why are you opening a new issue instead of replying to 
the already open issue ??

After some more debugging I'm now quite sure my problem is caused by the fact that 'orphan' is set to 3 somewhere.  
At the third batch (which shows item 5 and 6) LazyPrevBatch calls Batch.__init__ with parameters (sequence,2,-1,4,3,0). In function Opt these parameters result in execution of the branch 'elif end>0:'.
There 'start' is set to 3 (end(=4) + 1 - size(=2). 
Then 'if start - 1 < orphan(=3): start=1' sets 'start' to 1.

Because 'start' is set 1 here, in __init__ 'self.length' is set to 4 (self.end(=4) minus self.first(=0)). 

At the next batch, which shows item 7 and 8, 'end' is 6 and the problem does not occur. 

Remains the question: where and why is 'orphan' set to 3 ??
