Moving an indexed table with a small node cache fails

[faltet]

I've added a test on this (r3795). By running it, one can see what the error is:

$ PYTHONPATH=. python2.6 tables/tests/test_indexes.py BasicReadTestCase.test10c_moveIndex

I've commented out the new test (r3796) as it is not too grave (people should not need to work with too small cache sizes).

After the large refactoring on node management in the last few days, this already works. Hence, I've uncommented the test and added another one (for disabling the cache completely) in r3856.

Closing this ticket.
