I'll check out using xdebug. It's certainly fine when I comment out

Bulk deleting works. Thanks for the tip.
The weird thing is that I've just discovered that there's some other
problem on the staging server. There's an error with this line:
$aros = $this->Acl->Aro->find('all');
I can't figure out how to debug this. Processing stops right there.
In any case, your alternative cache config idea works for now, so
there's no need for the find() call. In the meantime, I'm going to see
about installing memcached.
