You could convert either mechanism into an event driven system by using a named system semaphore,

Your super agent would create the named semaphore and then wait on it.

Your other code puts the information required by the super agent into a "known place"; whether that is a db table or the file system; and then signals (posts) the semaphore to tell the super agent it has work.

A perhaps simpler mechanism would be to have the super agent listen on a port. The other code delegates work to it by writing the details of the task to that port; and the tcp stack does the queuing.

The downside is that work items aren't persistent across system failures. The upside is work items aren't persistent across system failures.
