That's right.  Paul Davis invented and implemented freewheel.  It
basically disconnects the JACK graph from the audio device and runs
cycles as fast as it can.  IIUC, this was primarily for rendering to a
file with ardour.

Using the example client...

 $ jack_freewheel y
 ...
 $ jack_freewheel n
 
The library interface is: jack_set_freewheel(client, onoff);

This doesn't work because the device is out of the loop.  As Steve
said, you can capture the result to another ardour track or use a
different recorder, like jackrec or ecasound.  But you can't listen
while doing it, so it's not very useful for mastering.
