What's required for a non-threaded AgentX++ subagent?

[Frank Fock]

James,

The ThreadPool creates threads only up to the size
of the pool. Once a thread of the pool is created
it is never canceled/destroyed until the ThreadPool
is deleted. Thus, with the latest AGENT++/AgentX++
your agent/subagent will not create/destroy threads
dynamically, even if you are using the default
setup.

Best regards,
Frank
