Summary: array.append is sloooow

Initial Comment:
array.append re'mallocs and copies each time an item is 
appended to it.  That makes the code below grind to a 
halt.  I stole the resizing algorithm from listobject.c and 
it speeds things up a bit.

>>> import array
>>> a = array.array('i')
>>> for i in range(10000000):
...     a.append(i)
...
