I'll second Doug's wish for the concurrency patch. Unless we're planning to have 2.4.25 out pretty soon anyway...
Also this is in Test: ITS#6736 Listener info destroyed too early on shutdown
Some issues it'd be nice to have in, if they're simple for those who know the code in question:
ITS#6760 rwm broken entry handling Fixed, I think, but needs review
ITS#6532 Support for common orderingMatching rules in extensible match filters TODO: Handle CSN and UUID ordering match too? (Almost certainly OK, but I wanted someone who knows to say so. It's a two-line update, setting the SLAP_MR_EXT flag for these rules.)
Also, possibly the rest of "ITS#6739 broken do_syncrep2()" is simple. Almost fixed.
