A whole bunch of people have been experiencing this over the past two or
three months, even without debugging features. I'd guess there've been
about ten threads about it so far. Nobody has been able to pinpoint
exactly what's going on. There seem to be two different problems:

1) The above "lag", including the fact that if you, for instance,
   extract a large tarball, playback slows down and stutters.

2) The crackling when starting to play a file. There are some other
   symptoms here too that I don't remember, but Kris and at least one
   other person are experiencing this.

Beyond that, several people (including me) noticed odd popping noises a
few seconds apart when playing any kind of audio. They're especially
noticeable if you play something fairly mellow.
