Try this. You only want to capture for a certain length of time, which
means a certain number of samples. So put a gr::blocks::head block
between the filter and file sink. The number of items you'll want is
going to be samp_rate (samps/sec) * time (secs) (and we know samp_rate
here is 1 Msps). That will store exactly that many samples and then
shut down the application.
