Years ago when I last had an SGI Irix system, cdrecord locked out all
other I/O and processes for about 10 seconds when it started burning a
CD. Not the 10 second countdown, but after that. If another cdrecord was
running on another device I'd bet that device would be starved during
this period. And that could be what you are seeing.
