Are there really any modernish OSes that *do* run out of memory? Stack
space (on those type of machines) maybe, but now we are talking programming
error, I would say, because that situation is foreseeable (and should be
expected) by the programmer. From what I understand, if one is programming
for embedded systems or iot-devices, dynamic allocation is not the common
way to do things and all memory required is allocated upon boot.

This quotes springs to mind: “In theory, theory and practice are the same.
In practice, they are not.”
