>>> import StringIO
>>> file = open("C:/Python20/readme.txt")
>>> fstr = StringIO.StringIO(file.readlines())

# The above line differs from the behavior of cStringIO, which correctly
# reports: "TypeError: expected string, list found"
# Doom is inevitable after this...

>>> len(fstr.getvalue())
838
>>> fstr.readline()
Traceback (innermost last):
  File "<pyshell#4>", line 1, in ?
    fstr.readline()
  File "c:\python20\lib\StringIO.py", line 85, in readline
    i = string.find(self.buf, '\n', self.pos)
  File "c:\python20\lib\string.py", line 172, in find
