I don't think you can;
as
threads::shared states:
bless is not supported on shared references. In the current version, bless will only bless the thread local reference and the blessing will not propagate to the other threads. This is expected to be implemented in a future version of Perl.
update Hmm... there seems to be
Pots::SharedObject, but as i look at the version number it's in early stages.
