Comment (by jinmei):

 trac1376 is ready for review.

 I believe this is a straightforward change.

 One possible point to discuss is that it doesn't work with older
 versions of sqlite3 database files (which don't have the "diffs"
 table).  I think we should discuss how to handle this in bind10-dev.

 The tentative proposed changelog entry is this:
 {{{
 320.?   [func]*         jinmei
         b10-xfrin now installs IXFR differences into the underlying data
         source (if it supports journaling) so that the stored differences
         can be used for subsequent IXFR-out transactions.
         Note: this is a backward incompatibility change for older sqlite3
         database files.  They need to be upgraded to have a "diffs" table.
         (Trac #1376, git TBD)
 }}}
