boolean function parameter like this is hard to read. 

http://www.chromium.org/developers/coding-style#Code_Formatting

Begin to prefer enumerated values (e.g. "DELETE_AFTER_USE/KEEP_ALIVE_AFTER_USE")
to booleans ("bool delete_after_use") as function arguments the more the

     cache_->RequestInitializeOnUIThread();
     test_util::RunBlockingPoolTask();
   }
