comment What do I do when I get an “Iterator does not have appropriate bounds” error?
@Szabolcs I don't currently have access to such a system. Also, it seems it'll take quite some time to check more than $2^{31}-1$ iterations. I hoped you might know from some docs.

Is this max number of iterations the same on x86-64 systems?

@AndrewNeitzke, it's not limited to laptops. It happens to me on all my desktops as well as netbooks.

@Cory don't forget that you can accept the answer if it solves your question.

comment Why does Mathematica simplify $x/x\to1$?
$\sqrt{x^2}$ is also defined for $x\le0$. It's the whole point of it — to be defined for all x (it's $|x|$ in disguise).

@Jens So how exactly do I use Assumptions for this? See update of the question.

comment Why does Mathematica simplify $x/x\to1$?
Here it's not a problem: D gives an expression, which is undefined for $x=0$. It's quite a correct result for function, which isn't differentiable at $x=0$. But then simplifying it to $0$ makes it defined at $x=0$ too, which is incorrect.

comment Does a running evaluation continue after the PC wakes from sleep mode?
I never had any problems with computation with suspend/resume cycles, but beware of small problems with interface.
