Hi Mike,
Yes, of course I bless my object.
I even tried this, but I think it is the same as during the exit. 
my $o=new MyClass;
my $dbh=$o->opendb;
warn $o->{_dbh};
warn $dbh; # the same as the previous line
undef $o;
exit;

I cannot put it as a lexical in the sub because I have just written an entire framework (+5000 lines), consisting of a tree of packages in OO, and setting the DBI object as an attribute has an advantage of using persistant DB connections.

This is the actual opendb routine 

sub opendb {
   my $self=shift;
   local($@);
   if ( not $self->{_dbh} or not $self->{_dbh}->ping) {
      eval{ $self->{_dbh}=$self->{_dbi}->connect() ; } ;
      if ( $@ ) {
         $self->Log('!',$@) and die "db gives error" ;
         }
      }
   $self->{_dbh}->{LongReadLen}=100000; # to handle Long column types
   $self->{_dbh}->{LongTruncOk}=0;   # generates an error when the dat
+a is too long
   $self->{_dbh}->{AutoCommit}=0;   # Lets run transactional
   return $self->{_dbh};
   }

And I call this opendb as much as I like, without going to the db everytime. (note $self->{_dbi} is a object from my superclass of DBI). And the link to tilly's one, that was the one I was referring to, but using flyweightwrapper is a bit overshooting, I think.
