Let us know if (and how:-) it works, please. (I'm very interested.)
I just tried it the other day. It's surprisingly easy to use and you
can simulate a lot of conditions.
Documentation is lacking, but this wiki page helps a lot:

You may need a pretty modern kernel. I hit a crash bug in one of
RedHat's customized 2.6.9 kernels. The people on the netdev list
mentioned a chance since then that may have fixed it. Haven't tried
it yet, but the same operation worked fine for them.
