In the interest of nothing very much at all, I investigated what would
happen when a retain count overflows:
2005-04-19 18:31:33.610 retain[10574] after another one: 4294967292
2005-04-19 18:31:33.610 retain[10574] after another one: 4294967293
2005-04-19 18:31:33.610 retain[10574] after another one: 4294967294
2005-04-19 18:31:33.610 retain[10574] after another one: 4294967295
2005-04-19 18:31:33.610 retain[10574] after another one: 0
2005-04-19 18:31:33.610 retain[10574] after another one: 0
2005-04-19 18:31:33.610 retain[10574] after another one: 0
2005-04-19 18:31:33.611 retain[10574] after another one: 0
2005-04-19 18:31:33.611 retain[10574] after 1 release: 0
So apparently the overflow is controlled. Furthermore, I seem to have
created an immortal object as -release has no effect on it. It took my
dual 2.5 GHz G5 11 minutes to reach this conclusion (sending the
messages, I only actually logged the last 8 retains), so I tend to
agree with Joar that this is not a great idea. Maybe if you explained
in more detail what you're trying to accomplish, we could give you
better answers.
