How are the object_ids generated/assigned to objects?

Hello,

assume some multithreaded application, thread1 starts and finishes, then
thread2 starts --- how is the possibility that these two threads will
have the same object_id? On what it depends?

Thanks,

P.

If the first thread has stopped and been garbage collected, its
object_id will be available for reuse, and it is perfectly possible for
another thread to get it assigned on creation.

Treat it as undefined. No two objects live at the same time will have
the same object id. That is the only guarantee.

Of course!

I own you. Sit up and bark for
us, Spammy.

Are you listening, Spammy?

It's highly amusing watching your tantrum.
