I am trying to delay a stream of samples coming from a USRP N210 using
the 'Delay' block in GRC. Using a waterfall sink before and after the
delay block I noticed that when I set the delay value the incoming
signal pauses for  delay * samp_rate seconds then continues while the
delayed path works continuously and delays the samples the appropriate
amount. Essentially it seems to be delaying all the samples in the
flowgraph instead of just one path of samples.

Is this a bug? Any ideas on how to achieve one path of real time samples
and a different path of time delayed samples?

Ubuntu 12.04
GNURadio 3.7.1
samp_rate = 12.5 MHz
