So, the benchmark rx uses time stamps to measure the packet loss.
Because the timestamps are emulated for usrp1, this measurement is going
to be very flawed. See
http://www.ettus.com/uhd_docs/manual/html/usrp1.html#missing-and-emulated-features
In any case, I fixed the problem with the benchmark locking up w/ USRP1,
just give the master a pull. It turns out that the emulated time needed
to be initialized or the loop would never quit.
