There's no point in even returning an instance. Just return the package name:
package DBconnector; my $dbh; sub new { return __PACKAGE__ } sub connect { my $pointless = shift; $dbh ||= DBI->connect($@); }
and so on.

[tye]: disable /proc and then see what it does?
[davido]: then it reads from /etc/passwd to decide who my uid is.
[davido]: sorry, typed that before you asked me to disable proc
[davido]: but you stumped me; don't know how to disable proc.
[tye]: I don't know if you can just dismount, but I thought so.
[davido]: yeah, umount -f isn't powerful enough.
[tye]: probably something in the init subsystem that does the mounting that you could disable and reboot.
davido needs to close laptop to board flight home from yapc.
[davido]: I'll look into it in a few hours probably.
[davido]: when i do get to that point I think I'll do it in a vm snapshot just in case. :)
