Replying to self- here's another case on the USRP2/UHD-
TX Path: Sig Source -> UHD (USRP2) Sink
RX Path: UHD (USRP2) Source -> Band Pass Filter -> Scope Sink
It seems that any kind of filter, even with appropriate calculation of
the rate coming out of the filter taking into account decimation wi

USRP1:
- When we have a very simple flowgraph with a USRP1 sink connected to a
signal source and a USRP1 source connected to a WX scope- trying to shut
down the app using the close box causes the USB on the host system to
freeze up requiring a reboot. Yanking USRP power or ctrl+c'ing avoids
this pr
