No idea about that either (I think Michael Stahl has previously been 
exposed heavily to locking, maybe he has some input), just two comments 
on the patch:

can be reduced to

(I haven't announced this new C++ API yet, as some issues about 
change-notification are not yet completely thought out for it.  Shame on 
me, should really do that soon.)

And

should instead set "UseLocking" to false, right?
