While its a big flow graph, there arent very many different types of blocks (10 of them are instantiated 19 times). However I've seen some segfaults before that I've identified as coming from the wav_file sink... I havent yet had a chance to look at the actual code to see if anything sticks out (and I'm not sure that I'd even be able to identify something sticking out ;) ).

Well, here's a flow-graph that exercises "valve" with WAV file sinks--8 of them.  The valves are
  operated randomly, with a state-change possible at a rate of 10Hz.   It doesn't crash on my
  machine (currently, an ancient dual-core laptop).

It uses a signal source, rather than UHD.  The signal source operates at 50Khz.
