Why is it recommended that the swap partition size be double that of the RAM size?
Specifically, why would I need to store data stored in the RAM twice??

You'll need minimum 1 X your memory size if you suspend-to-disk (hibernation), and add enough spare for usage of 'swapped' memory which goes....
Swap partition having double the memory size is just a general guideline, not a hard and fast rule.

Recently I've noticed that the following statement is not true given std::string s .
s.max_size() == s.get_allocator().max_size();
I find this interesting, by default std::string will use std::allocator<char> which has a theoretical limit of size...

So I just was testing the CLR Profiler from microsoft, and I did a little program that created a List with 1,000,000 doubles in it. I checked the heap, and turns out the List<> size was around 124KB (I don't remember exactly, but it was around that...
