I thought that use of the O_EXLOCK flag in the open(2) system call would prevent other processes from opening the file, but (at least on my Mac) it just blocks until the first process closes the file. Perhaps there are some other flags you can use to cause the second open(2) call to error out. Skip -- https://mail.python.org/mailman/listinfo/python-list
