I've come to realize something, but I'm not sure if I could be right:
Maybe the instructions are interrupted because there is a lack of virtual
memory. I mean is there not a limit to the memory the script can use? It
would explain why the script goes on, as when the instruction is
interrupted, all the memory taken by it is released.
I don't know if I was clear about what I wanted to say...
