I haven't looked into this properly, but I suspect that the solution
is to rework the USM table to take proper account of the engineID.

I don't quite follow.
The agent will read the trap information from the "trapsess" entry.
Every time you start the agent, it will re-read this directive, and
set up a trap destination accordingly.
  How is that not persistent?

If you're using informs (rather than traps), then you don't need to
explicitly create the user within the agent.

Can you explain a little more precisely exactly what you're
trying to do here.
  (I'm quite happy to believe that there may be problems, but I
don't yet have a clear idea of the exact scenario you're working with).
