Ed, 
  I have committed your makefile and lmc changes.

I don't even feel comfortable trying your patches to the vorbis decoder
at the moment. I am having a hard time believing this is the right
direction to take the vorbis decoder.    I, for one, prefer the clarity
of the old decoder.    I think more work needs to be done to understand
*why* the current(old) decoder fails on fast track switching. Was it a
race condition in the vorbis lib that you were working around?
Can you pinpoint the code that causes the race?
