[Discuss-gnuradio] benchmark_loopback.py in discontinuous mode results in transmission errors

I am playing with benchmark_loopback.py.
For continuous mode, it seems ok except the first packet is erroneous,
which I assume is due to initial state of the receiver.
But for discontinuous mode, I found most of the packets are in errors.
I used default values for all parameters.
Does that mean the demod cannot synchronize to the received signal
quickly enough? So for each burst of 5 packets, the first few packets
are incorrect due to slow synchronization?
However, according to the output, the error pattern seems random, not
necessary the first few of each burst.
I tried benchmark_qt_loopback2.py, which hangs up after transmitting 5
packets (dead lock?)
This really confuses me. Is it bug or something else?
