I noticed test_close_open_print_buffered(test_file) sometimes crashes on release26-maint branch. This is most problamatic part in my python2.6 test survey on VC6 + Win2K.

Here is stacktrace.

_write_lk(int 6, const void * 0x00b49240, unsigned int 11) line 155 + 3 bytes
_write(int 6, const void * 0x00b49240, unsigned int 11) line 79 + 17 bytes
_flush(_iobuf * 0x102618e8) line 162 + 23 bytes
_fclose_lk(_iobuf * 0x102618e8) line 130 + 9 bytes
fclose(_iobuf * 0x102618e8) line 67 + 9 bytes
close_the_file(PyFileObject * 0x00a9e6b8) line 370 + 7 bytes
file_close(PyFileObject * 0x00a9e6b8) line 570 + 9 bytes
call_function(_object * * * 0x00fdf350, int 11134648) line 3734 + 204 bytes
PyEval_EvalFrameEx(_frame * 0x00b33d50, int 131) line 2414
(snip)

Python crashes when MSVCRT touches internal buffer of file object via flush() in close().

I think this is multi-threading bug related to internal buffer of file object. I'll post more.
