This bug is still open, so please post your new test case under this bug.  This
is my number one priority right now, so I hope to have a fix soon.

As for your large buffer case...are you using the latest ns-3-dev?  There was a
fix pushed that addressed an issue that sounded identical.  The hang was in the
PacketMetadata code.
