I might have a look at these later.  I basically wanted to see the
effect of a large number of slow concurrent connections on the
application.  The problem is obviously producing the load without DOSing
the load generator.  I was thinking that something like the load
generator from the "unified concurrency model"[1] article might work as
it appears it implements the tcp stack in userland.
