 Build 760, G1G1.

 I installed 760 and used it a bit, perhaps made a friend out of another XO
 to try to test sharing, then left it sitting for a few
 days, closed it into suspend, stuffed it into my backpack, carried it
 around in suspend for two days, noticed the red battery light, pulled it
 out and powered it until the battery light was green, then a day later,
 opened it and tried using it.

 It was pretty unusable.  A friend tried to launch Analyze, and the
 throbber sat there for many, many seconds, and then just disappeared and I
 got the donut shell again.  I could not bring up the control panel:
 clicking on that menu item did nothing.  No error report, no nothing.

 I switched to the text console, determined using "top" that it  was out of
 usable memory (despite having NO activities running!), inserted an SD
 card, made a swap file on the SD card with "dd" and "mkswap", and did
 "swapon" it.  This gave me enough breathing space to run the control panel
 and confirm that I am indeed running the 760 release candidate.

 "top" shows the sugar-shell process with 141MB total, 105MB resident,
 taking up 45% of the available DRAM (235MB).  (I now have
 34MB total pushed out into the swap file.)

 Currently, the Frame shows no network icon at all.  None of the power
 management options are checked.  ifconfig reports that I have a link-level
 v6 address on each of eth0 and msh0, but no other IP addresses.  I do not
 know what the last network configuration that I set was.  The Network
 screen doesn't show current status, of course (that's in the Frame now, or
 rather, it isn't), but it shows a variety of access points.  My usual
 access point appears, with a little star on it, and no white circle; I
 have no idea what this means.  No XO's appear in the Network display.  In
 the Friend display, a second XO appears, along with a copy of Browse.
 When I hover over the second XO, its name appears.  Nothing happens when I
 hover over, or click on, the Browse icon.

 I do not know what kind of leak this is -- nor how to diagnose it -- but
 it sure does make the system unusable.  I'll let it sit this way for more
 hours, in case someone comes along who wants to diagnose it.  (I could
 probably plug it into Ethernet and then somebody could ssh into it to poke
 around if they wanted.)
