I have a decorator which takes an optional argument that tells me 
whether I should use locks.
Maybe I could import 'threading' only if needed. If the user wants to 
use locks I'll assume that 'threading' is available on his/her system. 
By the way, should I avoid to 'import threading' more than once?

Thank you so much for answering my question.
