I've just noticed 6.2 seems to be a little better on this than 5.1. (Since I just upgraded.) But if you hit indirect lighting, have multiple light sources, a transparent and/or reflective material, and do anything with caustics, the memory usage can climb fairly quickly into the unstable range. For more "regular" scenes, not so much. This is also easier to have happen if you multitask (doing light things like browsing/email) while rendering in the background.
That garbage collection thing is probably true though, since if you can wait long enough (like another day at least) the memory use may go back down when done. (When not using the batch method mentioned.) But it's best to not let it hit virtualmem territory in the first place. (Having an extra GB or using newer hardware probably helps alot.)
