Summary: Memory leak on open() only in 2.3?

Initial Comment:


If  for instance /tmp is a directory, then the follwing
code fragment produces a large memory leak on Python
2.3 compiled on Linux 2.4.20. This does not appear to
be a problem with previous versions of the interpreter.


#!/usr/local/bin/python


while 1:
    try:
        open('/tmp')
    except:
        pass

It appears that the exception IOError: [Error 21] Is a
directory leave garbage. If the parameter to open()
does not exist, the problem does not occur.

Over the weekend and through Monday I ran my system 24/7
with the previously attached code. There do not seem to be
any problems, but I am waiting for your "blessing" before
considering it a fix.

I think I may have a fix. Check out the attached file. It
seems to work for me.

Wow, it sure does leak!

Checked in as:  Objects/fileobject.c 2.180

Still needs a test.  Leaving open until I get around to it.
