[New-bugs-announce] [issue6242] Fix reference leak in io.StringIO

[Alexandre Vassalotti]

New submission from Alexandre Vassalotti <alexandre at peadrop.com>:

io.StringIO does not clear its reference to its attributes dictionary
when deleted. This causes a leak when io.StringIO has attributes. 

>>> def leak():
...    for _ in range(100):
...      f = io.StringIO()
...      f.foo = 1
... 
[39348 refs]
>>> leak()
[39650 refs]
>>> leak()
[39950 refs]
>>> leak()
[40250 refs]
