I'm aware of that, but I really don't see any excuse for this much
splotchiness with that many samples. Even the bright areas near the
"light" are noticibly uneven, and unless someone has a better
explanation, I blame the sampling method; maybe it's not random enough,
so the generated numbers tend to repeat themselves and the results don't
average out as well as one might expect.

The light isn't even really that tiny; imagine a glowing beanbag chair
crammed in a ceiling corner of your bedroom and you have a fair idea of
the proportions of the scene.
