 Trac #65 shows a jffs2 problem, I believe.

 When flash was small, it clearly made sense to defer GC of flash blocks
 pretty much as long as possible; it reduced flash wear, and the memory
 usage wasn't excessive.

 However, it looks like on our system, with much larger flash but
 relatively less memory, that we may want to start garbage collecting on
 flash to retrieve RAM sooner.

 In the short term, we'll move /tmp
 and /var/log off of flash, but we could have similar
 issues with "normal" applications).
