It won't speed things up unless the main thread is waiting for user
input during those imports, or something like that.  Threads in Python
don't really run in parallel.

Here's one way:

def importRest():
   global audio
   import audio as local_audio
   audio = local_audio
   # etc. 

There's surely other ways that are better.
