And you're seeing no CPU?

What about vmstat and iostat?
Especially vmstat, unless you're doing audio, network and/or
disk, then iostat.

It's hard to pin-point I/O usage in Linux, but even desktops
today can literally feel the pinch of I/O.

Well, _regardless_, I would run something like this:

  while true; do
    date >> /tmp/mystat.log 2>&1
    for i in `seq 1 100`; do
      vmstat 1 1 >> /tmp/mystat.log 2>&1
      iostat -d 1 1 >> /tmp/mystat.log 2>&1
      sleep 3 
    done
  done
