When slicing an IOBTreeItems object, the value returned has 1 too many elements.

For example, given a list l with 100 elements:

len(l{20:80]) returns 60

for an IOBTreeItems object iob with 100 elements:

len(iob[20:80]) returns 61

Attached is a patch for testBtrees.py which includes a test case for this which currently fails.
