     To make sure a data image is fully readable on any Linux machine, this
     function adds 300 kiB of padding to the (usualy single) track.
     Audio tracks get padded to complete their last sector.
+    A fifo of 4 MB is installed between each track and its data source.
+    Each of the 4 MB buffers gets allocated automatically as soon as a track
+    begins to be processed and it gets freed as soon as the track is done.
+    The fifos do not wait for buffer fill but writing starts immediately.
 
     In case of external signals expect abort handling of an ongoing burn to
     last up to a minute. Wait the normal burning timespan before any kill -9.
