[issue3125] test_multiprocessing causes test_ctypes to fail

roudkerk [EMAIL PROTECTED] added the comment: I am not sure to understand. Can you elaborate? How is memory management different between windows and unix? Removing the if win32 bits will not make shared ctypes objects picklable on unix. Even on windows there are only picklable in the context

[issue3125] test_multiprocessing causes test_ctypes to fail

[issue3088] test_multiprocessing hangs on OS X 10.5.3

[issue1378] fromfd() and dup() for _socket on WIndows

roudkerk added the comment: Currently on Windows set_error() make use of a large array which maps socket error numbers to error messages. This patch (against socketmodule.c from Python 2.6) removes that array and just lets PyErr_SetExcFromWindowsErr() generate the message by using the Win32
