Removed closure optimizations from the Wheel classes. The later addition of $wheel->event() subtly broke them.
Added poing.perl, a multi-host ICMP ping program, to the samples directory. My ISP was down, so I hacked this together, "borrowing" a lot of code from Net::Ping. As such, it's neither friendly to configure nor commented.
Sessions' "default" option didn't confess, contrary to the documentation.
