( Sorry, this post is completely wrong. )

That's a different problem, relating to threads and shared variables.

Is $alias_for a shared variable? I'm no threading expert, but it makes sense that captures do not remain shared. Perhaps you want to capture a reference to the shared variable instead of capturing the shared variable itself. 

    my $alias_for_ref = \$alias_for;

    eval "package $class;"<<'SUB';
        sub find_ids {
            my ($class,$params) = @_;
            # Do something with ${$alias_for_ref}
            return SUPER::find_ids->($class,\%params);
        });
