 // This file provides the core implementation of fileapi methods.
 // The functions should be called on UI thread.
 // Note that most method invocation of fileapi is done on IO thread. The gap is
 // filled by FileSystemProxy.
 // Also, the order of arguments for the functions which take FileSystemInterface
 // at the last is intentional. The instance of FileSystemInterface should be
 // accessible only on UI thread, but arguments are passed on IO thread.
 // So, here is an intended use case:
 //   1) Bind arguments on IO thread. Then a callback instance whose type is
 //      Callback<void(FileSysstemInterface*)> is created.
 //   2) Post the task to the UI thread.
 //   3) On UI thread, check if the instance of FileSystemInterface is alive or
 //      not. If yes, Run the callback with it.
