10139N/A

10139N/ANeed way to "dup" an rdataset (i.e. different rdataset handle, same underlying

10139N/Adata).

10139N/A

10139N/ADB addnode routine should take an rdataset *, which, if non-NULL, would be

10139N/Aattached to the added rdataset.

10139N/A

10139N/ANeed credibility, security status.

10139N/A

10139N/ACache security status in rdataset. Have rdataset supply methods to get/set

10139N/Athe security status. For RBTDB, it goes something like this:

10139N/A

10139N/A get:

10139N/A if (cached status == pending)

10139N/A lock node lock

10139N/A read rdataset's status

10139N/A unlock node lock

10139N/A update cached status

10139N/A return (cached status)

10139N/A

10139N/A set:

10139N/A require that status cannot go backwards (e.g. OK to pending)

10139N/A lock node lock

10139N/A write rdataset's status

10139N/A unlock node lock

10139N/A update cached status
