This sounds interesting. I haven't tried a complete IP router, but with a simplified one which doesn't care ARP and ICMP, it works well. Things may be different because I am using my own modified Click and it is hard for me to figure out which change makes this work in a short time..
I've got the same problem that after running Click once and killing it for a new settings, it was stuck so I had to reload the NIC driver and netmap module and re-setup the network configuration. But my performance result is good, for a simple forwarding configuration, it achieves a 13.1Mpps peak performance with a 10Gb Intel 82599 NIC on an old Intel Core i7 930 CPU (two of four cores used).
