ccache's cleanup algorithm

[Scott Bennett]

     In ccache's cleanup.c module, the comments say that files are deleted
from the cache on a LRU basis.  However, the code refers to mtime, not atime,
so it appears that ccache is, in reality, using a Least Recently *Modified*
basis upon which to expire files from the cache.  Is that really what ccache
does?  Or did I miss something?  If it's really using LRM instead of LRU,
can anyone explain why?
