[Discuss-gnuradio] Sample Delay

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
