Yes. They can share data, communicate in various ways, one thread can
start another, wait for another, etc.

I think this problem is a natural problem for threads. I mean, using
threads for this problem can make your program shorter and clearer.
You're simulating a bunch of independent but identical agents, so each
one could live in its own thread.
