Recompiling .pyx with pyximport failed

I wrote fib.pyx containing fibonacci funciton like that

def fib(int n):
    cdef int i
    cdef double a=0., b=1.
    for i in range(n):
        a,b = a+b, a
    return a

And I got pyd module with

import pyximport
pyximport.install()
import fib

It worked well. But when I edited fib.pyx a little and I tried to import it, then the change was not reflected without any error.
After I restart ipython, I tried

pyximport.install(reload_support=True)
import fib
fib.fib(10) # good result

# edit fib.pyx

from importlib import reload
reload(fib)

The reload was well because it succeeded to reload existing fib.pyd module. But I got the result of older fib function.

How can I recompile fib.pyx with import fib? Is it impossible?

Environment: 
Python 3.4.3
Windows 7
IPython 3.2.1

Try it with autoreload, if it doesn't work i am afraid you have to restart the kernel process.

[1]: %load_ext autoreload

[2]: %autoreload 2
