I think we can live without this feature. E.g., ppolicy, sssvlv etc. all just create their own private arrays of per-conn structures. Sharing here will require introducing another mutex.
Right, I've fixed things differently. I note that other code (e.g. paged results) is write-accessing its state without mutex protection; although it is unlikely that more than one search operation use paged response concurrently, this is incorrect in principle.
I'm closing this ITS.
