Why don't you use the threading module rather than the thread module?  It
provides a higher-level interface to threading.  Redoing your example
above:

import threading

def test():
    print "hi"
    sleep(1)
    print "hi2"

t = threading.Thread(None, test)
t.start()

BTW, this example is next to worthless since it's more or less the same as
calling the function outside of a thread.  This example is only slightly
more interesting:

import threading
import time

def test(value):
    for i in range(10):
        print value, i
        time.sleep(1)

ta = threading.Thread(None, test, None, ('A',))
tb = threading.Thread(None, test, None, ('B',))
ta.start()
tb.start()

You don't need an explicit return nor do you need to return anything.  When
the function finishes, it returns, that's what is meant.
