 On Q2C27 and build 593.

 I sort of have a "reliable" way to reproduce the problem, but it takes a
 few hours.

 I was trying to address the corner cases of #3547 and #3567.  If you start
 two Etoys, and instanciate "Camera" object and SoundRecorder object in
 each of them.  Then switch to the ring view and start Record.  It often
 fails to show the viewfinder.

 If you try these actions in different combinations (such as two Record and
 then Camera and SoundRecorder in Etoys, etc.), you might see the problem.
 In one occation, the system became very sluggish; apparently X was running
 but I could move the big cursor only every two seconds or so.  I pressed
 Alt-Ctl-erase and kill the X server, and saw a repetive messages to the
 console screen.  X and Sugar restarted and I could get the content of
 dmesg.  a part of it is shown in the attached picture.

 In another occasion, the system completely froze in the text console; it
 was showing the same thing in the picture but frozen.
