 Was trying to reproduce #8927 (but failed).  Was using Browse to surf
 [http://nytimes.com] , [http://kitco.com] , and [http://youtube.com].
 These sites all have numerous animated Flash-based advertisements or
 features, but Browse just shows Flash placeholder boxes with "click to
 play" messages, which I avoid clicking.  Nevertheless, while I surfed
 these websites, I watched # top -c  in console and many new /usr/bin/gtk-
 gnash processes were being started (owner = 10001 = Browse).  Each gtk-
 gnash process needed at least 2% memory and 2% CPU, sometimes much more.

 After about 1/2 hour of surfing (and in youtube.com), there were 12 gtk-
 gnash processes, my XO got slow, then Browse stalled for over 20 hours
 with no change.  I could still switch Sugar views, view the frame, and use
 a console, but Browse stayed stuck and unresponsive.  I have not seen this
 failure mode before.  (The most familiar situation is when everything
 freezes, until oom-killer eventually kills Browse and then the XO responds
 normally.)

 olpc-log coming...   somewhere I saw a logfile that said 'cannot allocate
 memory".

 I don't know if having 12 gtk-gnash processes running for one Browse
 instance is a bug or a feature.  Seems like trouble.

 After I did the olpc-log, I eventually did ctrl-alt-erase to restart
 X/Sugar, then the stalled Browse and the 12 gnash processes all
 disappeared and my XO now is running okay.
