For example you could import sys, publish an attribute on it, and another
script could read it. Or you could go in and change "min" or "max" in
__builtin__. Or you could go and mutate some read/write static field in
the .NET framework. Basically while everything is thread safe there's
no level of isolation between the scripts. It's probably nothing to be
too concerned about I thought I'd mention it for completeness.
