(Since this is in a semipublic interface that we're going to be stuck supporting for a while, we care about naming.. I agonize a lot about naming because I think that in the aggregate, it makes the difference between a system that feels clean and clear and fun, and a system that is sort of tedious or uninspiring to deal with. I have no scientific data to back this up but so far people put up with me :) I say "semipublic" because I wish `__meteor_bootstrap__` were 100% private, but in practice people read the code, find it, and use it to perpetrate all kinds of gruesome hacks. One day we will get rid of it, but it's going to take a few refactorings..)
