Comment(by jinmei):

 cache_unittest:
  - please don't hardcode flags (e.g. for the second arg of
    HotCache::cache()), even though it's opaque for the !HotCache
    module
  - the LRU test is insufficient.  this essentially only tests the
    upper limit of cacheable entries.  I added a test for the LRU
    feature (r2134).
  - C-style cast "(time_t)" seems redundant.  If we really need it, the
    use of it is inconsistent in the .cc, and in that case we should
    use C++ style cast (after rethinking the design several times).  I
    removed them in r2135.
