So, a "hack" that could be put into UHD (or perhaps gr-uhd) is that if
we've sent N
  consecutive blocks of zeros, we cancel the "burst", and resume only
when we see
  non-zeros.  This is conceptually similar to the way analog T/R relays
that rely on
  power-sensing work.

But yes, a cleaner mechanism would be if one could insert a "don't
transmit this, I'm just keeping
  the stream alive" tag in the TX datastream.
