Okay, so here's the more concise version for posterity / future googlers...

import threading

def run_in_thread( func, func_args=[], callback=None, callback_args=[] ):
    class MyThread ( threading.Thread ):
        def run ( self ):
            result = func(*func_args)
            if callback:
                callback(result, *callback_args)
    MyThread().start()
