Now that maxTickDepth no longer exists there's no depth index on
infoBox. Forgot to remove the comment about this.
// this infobox thing is used so that the C++ code in src/node.cc
// can have easy accesss to our nextTick state, and avoid unnecessary
// calls into process._tickCallback.
- // order is [length, index, depth]
+ // order is [length, index]
// Never write code like this without very good reason!
var infoBox = process._tickInfoBox;
var length = 0;
