I cannot replicate this behavior (64 bit Linux). Last line returns x for me.

comment Why does Mathematica list the variables in a double integral backwards?
@RahulNarain The issue that OP has (which I must admit I empathize with) is that Integrate[x+y,{x,0,a},{y,0,f[x]}] refers to an integral $\int_0^a\int_0^{f(x)}(x+y)dydx$. The inversion of the $dydx$ terms with the iterator may seem unnatural to some.

You beat me to the second one. I didn't find it much faster, though. One thing that sped it up slightly is Flatten[..., 1]
