It looks like TFW has a destructor that should close the file (it
shouldn't matter if the file gets synced as long as it gets closed
unless the whole system crashes).  I went up one level to the RingBuffer
class and that has a destructor which deletes the TFW that it spawns, so
that should be ok.

Going up from there looks a bit messier.  Basically we need to make sure
that anything that creates a RingBuffer deletes it when it is done.

If I just stick a printf in the Ringbuffer constructor/destructors, will
that make its way into the logs?  What is the best way to log a simple
message in myth?  I want it to always log - I don't want to have to
enable all debug messages to see it...
