Did you know that global variables are only global to the module?

This will bind the names thread1 and thread2 in the importing module, i. e.
you have now two distinct thread1 variables no longer pointing to the same
object after a thread1 = something assignment in one of the modules. Do 

import subfile

instead and access the variables with qualified names

subfile.thread1 = something

in all modules except, and everything should be OK.
