I read through the source code for this module... There are at least two bugs I can see where any parameters you pass in the call to "tie" will not be used.
You should contact the author and let him know what is happening.
I think pushing onto a shared array would have to be done like this:
if ($ns->lock()) {
my $var1 = $ns->getvar('var1');
push (@$var1, 'another item');
push (@$var1, 'yet another');
$ns->setvar('var1', $var1);
$ns->unlock();
}
However, that seems to trigger a bug somewhere too.
FWIW, you should be able to use the "reuse => 1" parameter to warn yourself of the problem you were having (creating a new namespace under a different name when you meant to open an existing namespace)
