Absolutely amazing!!! Not two minutes after sending the previous email
I got two xruns clustered together:

nperiods = 2 for playback

subgraph starting at ardour timed out (subgraph_wait_fd=20, status =
0, state = Finished)
14:06:43.636 XRUN callback (1).
14:06:43.637 XRUN callback (2).
**** alsa_pcm: xrun of at least 0.728 msecs
**** alsa_pcm: xrun of at least 5.548 msecs

The machine had been essentially 'User space idle' for the previous
two hours. The screen saver had kicked in. Audio was running and the
machine was busy. I woke it up, gave xscreensaver my password, read
email, sent the previous mail, then picked up the telephone to make a
call. Not 2 seconds later the xruns occurred!

Bizarre!!!
