Oddly, there doesn't seem to be much effect on speed whether I use a
single random number generator (i.e., instance of java.util.Random)
or one for each thread.

I'm surprised to hear this. Do you have a single random number
generator? In housebot, Each thread has its own random number
generator instance. Besides avoiding a bottleneck as each thread
generates random numbers, it also opens the door for repeatable
behavior in a single worker thread.
