Comment(by bernie):

 Replying to [comment:1 tomeu]:
 > I kind of remember that the disk cache was removed from the shell
 because the kernel has already an I/O cache and we were duplicating it.
 The rationale with test results should be somewhere in dev.laptop.org
 and/or the mailing list.

 I would agree that caching the plain text is useless.


 > Often-used icons should be in the surface cache so we shouldn't hit the
 disk unless this cache has been overflown.

 This is what does not seem to be working: the sugar-session process seems
 to be reloading icons that should stay cached. If the frame icons are
 purged from the cache, there's a considerable delay every time the frame
 is being shown.
