[Pharo-users] Building agents in Pharo

I am interested in building a system that uses co-operating agents to parse events. Is Pharo a suitable system for this? I ask because given that it is single threaded, I wondered whether running multiple agents would present any sort of problem. Has anyone got experience of building something like this? And, if so, what did you use for your basic queue? Is there a suitable FIFO style queue within Pharo? Cheers Andy
