Strange strxfrm behaviour?

[Tomaž Ficko]

Is this normal strxfrm behaviour? Shouldn't strxfrm return the same result 
for same agrument everytime it's called.

>>> locale.setlocale(locale.LC_ALL, "")

>>> s = 'a'
>>> d = {}
>>> for  i in range(1000):
...     sf = locale.strxfrm(s)
...     if d.has_key(sf):
...         d[sf] += 1
...     else:
...         d[sf] = 1
...
>>> print d

'\r\x01\x02\x01\x02\x01\x18\x08\x10': 76}

What is going on here. Any hints?

Thanks
