If you're ever planning on sending a SIGINT (^C) to the program, then
yes, you will need to properly handle the signal. See
usrp2/host/apps/rx_steaming_samples.cc for an example.
Do you have the usrp2 serial console hooked up?
Is it reporting anything? It's possible that it's getting wedged
somehow. (If so, the console is ususally streaming a bunch of "EEEEEE..."s)
