I've got a few specific tests of the new functionality in the usernstest.c
in the nsexec package at
https://launchpad.net/~serge-hallyn/+archive/userns-natty/+sourcepub/2530252/+listing-archive-extra .
Of course LTP already has a good set of test cases for the regular
functionality.

It's good to look at output of 'id' in the task versus 'ps' from the initial ns,
as well as create a file and look at the stat output from both namespaces.
