This is true of virtually all software, virtually anywhere. It's
possible to write software that *assumes* that its data memory will be
initialized for it to all zeros, and if the OS doesn't automatically do
this then the program will appear to work only on a freshly powered-up
machine. Such software should never make it through QA to release....
