Might as well ask for the numSubordinates operational attribute to be 
implemented instead, this doesn't seem to merit a new exop. And for 
numSubordinates, see the -devel archives for why we chose not to implement it.

In either case, the server still needs to iterate over all entries internally, 
and the result has to take ACLs and entry disclosure into account.
