You seem to be asking for a way to stop a program doing exactly what
it's written to do. I don't know what kind of answer you expect.

Indeed. In this case, the program is written to gobble up memory, and
the operating system kills it. To “circumvent” that behaviour surely
reveals the problem: that the operating system isn't handling processes

If you use Python 3 instead of the obsolescent Python 2, the ‘range’
callable has this sensible behaviour by default.
