Situation
This TID explains how to turn off caching script variables so that multiple threads can use the same script if required.
Resolution
Put the following entry in ~MO/config/Formula.custom.properties (Please create Formula.custom.properties if it doens't exist).
Script.LoadCacheDisabled=true
Disables caching and should protect things - but does cause a performance hit, so only use it as a last resort.
