The point is to use Swift itself _and_ Keystone, in order to find
discrepancies or "orphan" accounts. I ended using listdir for now,
since our installation is very small, so directories fit in memory.
Code is here:

Output looks like this:

"S" is for accounts found in Swift, "K" is for accounts found in Keystone.

I have a feeling though that I must be reinventing the bicycle here.
Surely someone, somewhere, have written a Swift consistency checker
before.
