I tried, but it still crashed. I could reproduce the crash by following
script. It crashed also on Python2.7, but it doesn't crash on Python3.
And when I used io.open() instead of builtin open(), it doesn't crash
even on Python2.x. (Probably because io.open implements buffer protocol
by itself)

size = 1024 * 1024 # large enough
f = open("__temp__.tmp", "w", size)
for _ in xrange(size):
f.write("c")
t1 = threading.Thread(target=f.close)
t2 = threading.Thread(target=f.close)
t1.start()
t2.start()
t1.join()
t2.join()
if __name__ == '__main__':
main()

I lied a bit on msg110655. close(2) is not used, that is actually
fclose(). I didn't notice the variable *close* was declared as
the parameter of fill_file_fields().
