 On XO-1.5 laptops which are disk space challenged (thanks to #9964), I am
 seeing suspend/resume fail as disk space is gradually reduced.

 I'm running OS64, on C1 laptops with a 2GB SD card installed.

 After a fresh install, the disk space on / is:
 /dev/mmcblk0p2   total: 1831852   used: 1657920   free: 155324  92% /

 After removing both Wikipedia activities:
 /dev/mmcblk0p2   total: 1831852   used: 1436292   free: 376952  80% /

 After installing the test files:
 /dev/mmcblk0p2   total: 1831852   used: 1698788   free: 114456  94% /

 After running the suspend/resume (and SD wear) test for many cycles, the
 disk space on the root partition has been reduced by over a hundred MB.

 After a machine failed due to lack of disk space, it was rebooted, and
 continued to show a lack of disk space.   It automatically deleted both
 Scratch and EToys, then booted.   The difference in disk space seems to be
 accounted for somewhere in /versions.
 On a fresh install, du -sk /versions/* shows 270MB in /versions/run, on
 the one that failed due to lack of disk space, the same command shows
 402MB in /versions/run.   On both laptops, du -sk /versions/run/* reports
 the same (1.4GB in /versions/run/642/).

 This bug is very repeatable.
