I can't think of a way to measure the actual time from (good samples received) 
to (good RF transmitted) without a lot more setup and some kind of timestamped 
signal to receive, but the time spent by the control thread (i.e. the python 
code you actually see) to perform the switch, which includes the time to 
_construct_ the source and sink blocks and therefore reinitialize the HackRF 
hardware, is on average:

tx->rx: mean 59 ms
rx->tx: mean 73 ms

I suspect these numbers will be highly platform-dependent. I'm using OS X 
10.9.5, and a somewhat old version of gr-osmosdr (before the multiple device 
support patch, which I imagine might affect the thing I'm exercising here).
