Dear Monks, I am writing an embedded Perl program. The embedded module is suppose to return an object, (blessed hash ref, for example) and I use this object to make the calls.

Now came the requirement for threading. this said object creates threads as workers.
To my suprize, I found out that the object itself is being copied to the worker threads, and destroyed then they are destroyed.
How can it be? I scanned my code, and I don't keep this object ref inside Perl, but in SV* on the C side. I thought that it is completely safe there.
How do I protect my SVs so Perl won't duplicate them when it create a thread?
(in perl it's easy. just make sure it's not a global)

Thanks,
Shmuel.
