I'm pretty sure I fixed the slice copying problem through a
__deepcopy__ overload a long time ago elsewhere. I don't think these
tests should be excluded from the test run yet. Perhaps we should run
the 2x tests from py27 down to 2.4. Tests in newer python's are less
likely to fail.

Do you want _refactor_indexnode merged for this release?

I'll try to find some time this week.
