Which brings you back to Robert's original question:

There's no real difference between the master agent and a subagent here.
If you're talking about a (sub/)agent handling multiple requests in
parallel, then that requires the MIB modules to be thread-safe.
Now I'm no expert in the problems involved in threaded-programming,
but it strikes me that there are two basic interactions that need
to be considered:
a) the MIB module code with the main agent driving code
b) one MIB module with another
I'd be tempted to tackle these separately - first work on the
MIB<->agent interaction (with the MIB modules tested deliberately
chosen to avoid inter-MIB-module dependencies).
Then once that's working, there would need to be a means of
denoting particular groups of MIB modules as inter-dependent,
and hence ensuring they weren't processed in separate threads.
But how much it is sensible to "bolt on" to the existing code,
and how much this would involve a significant restructuring
of the overall agent code, I wouldn't like to say.

Oh, it's definitely a worthwhile task, and I wish you well in it!
