* overhead of shipping all I/O traffic across IPDL. Example: JAR files.
*
* To open a file handle with this class, AsyncRemoteFileOpen() must be called

* result is NS_OK, nsIFile.OpenNSPRFileDesc() may be called--once--to get the
* file handle.
*
* Note that calling Clone() on this class results in the filehandle ownership
* being passed on to the new RemoteOpenFileChild. I.e. if
* OnRemoteFileOpenComplete is called and then Clone(), OpenNSPRFileDesc() will
* work in the cloned object, but not in the original.
*
* This class should only be instantiated in a child process.
