- Stop source thread if max sim time is reached
- Don't put agents in sources, before the content of queues is generated
- in the _building

Source thread updates the Queues, but the building is not updated yet.
That leads, to the same agents will be generated by the sources
and added to the Queue.
The queue will be emptied in the main thread.

Therefore, the source thread should not iterate again, unless the
main thread empties the queues and updated the building pointer
