new test case updated to the latest API

I evaluated your test case, and I seem not to get any hang at all:

And it exits normally at that point.  I had to SLIGHTLY modify the code you
posted to make it compile under a few helper API changes, and I removed the
GetUid API of your tag class, as it appears this is incompatible with the
newest ns-3-dev and didn't appear to be used in this test case.  I've attached
my updated version.

Can you confirm that you are still having the same hanging issue?
