BSS works great if your maximum memory allocation needs are
deterministic and you can calculate them prior to compilation.

And there is a *tiny* cost to grossly overallocating in the BSS section
- the OS still has to set up the page tables and the system consumes
*real* memory for those entries. Though this is such a ridiculously
small cost that it probably isn't worth mentioning.
