After a quick scan of this thread, I didn't see the actual source for your
call to the file's close(). Is it perhaps "file.close" and not
"file.close()"? Forgotten parentheses won't give an error and won't close
the file.
>>> f=file('blah.txt','wt')
>>> f
<open file 'blah.txt', mode 'wt' at 0x00ECB9F8>
>>> f.close
<built-in method close of file object at 0x00ECB9F8>
>>> f
<open file 'blah.txt', mode 'wt' at 0x00ECB9F8>
>>> f.close()
>>> f
<closed file 'blah.txt', mode 'wt' at 0x00ECB9F8>
>>>
