the module threading gives an easy to use interface for threads.

t = threading.Thread( target=bgjob_fu, args=("arguments",) )
t.start()

you can't "exit" the gui by terminating python but you can close all
windows and free memory by deleting unused objects with "del" and then 
after all that use

t.join()

to wait for the background job to finish.
