I wrote the below code

    def _use_gb_ram(num_gb):
        u'\n                                Function    to    consume    GB    of    memory\n                                '
        import sys
        bsize = (sys.getsizeof(u'        ') - sys.getsizeof(u'    '))
        boffset = sys.getsizeof(u'')
        num_bytes = int((num_gb * (1024 ** 3)))
        gb_str = (u'    ' * ((num_bytes - boffset) // bsize))
        assert (sys.getsizeof(gb_str) == num_bytes)
        ctr = 0
        while (ctr < 30000000.0):
            ctr += 1
        del ctr
        del gb_str
    from multiprocessing import Process
    from threading import Thread
    num_gb = float(num_gb)
    thread_list = []
    for idx in range(num_threads):
        thread = Thread(target=_use_gb_ram, args=((num_gb / num_threads),), name=str(idx))
        thread_list.append(thread)
    print((u'Using    %.3f    GB    of    memory    over    %d    sub-threads...' % (num_gb, num_threads)))
    for (idx, thread) in enumerate(thread_list):
        thread.start()
    for thread in thread_list:
        thread.join()

What's a good function header?
