This is needed if someone needed to perform an action (add/remove) a
single memory section. The 'split' option allows users to isolate
a memory section  so these operations could be performed.

The idea of being able to split a directory came out of a previous
discussion on how to resolve the issue this patch set is trying to solve.
I included the split functionality in this patch set since it
was suggested.  I will leave the decision of whether or not this
functionality is needed up to the community.
