input() throws SyntaxError

[ironpythonbot]

Input() throws an EOFError when stdin is StringIO() in CPython2.5, but IronPython throws a SyntaxError. like below code:
import sys
import cStringIO
sys.stdin = cStringIO.StringIO()
input()

CPython result :"Traceback (most recent call last):
File "C:\Documents and Settings\v-juwa\Desktop\test_input.py", line 5, in
input()
EOFError: EOF when reading a line"

IronPython result: "  File "", line 1
^
SyntaxError: invalid syntax"

And input() throws RuntimeError when delete stdin or stdout module in CPython2.5, IronPython throws a SyntaxError. like below code:
del sys.stdout
input('Prompt')

Cpython result:"Traceback (most recent call last):
File "C:\Documents and Settings\v-juwa\Desktop\getattr.py", line 3, in
input('Prompt')
RuntimeError: [raw_]input: lost sys.stdout"

IronPython result:"Prompt
File "", line 1
^
SyntaxError: invalid syntax"

import sys
import cStringIO
sys.stdin = cStringIO.StringIO()
input()

del sys.stdout
input('Prompt')

del sys.stdin
input('Prompt')
