Sorry, I should have given some context to that.  I'm being asked by
clients to evaluate LMDB as a backend choice because the apparent DB
size (2.4GB) of a large AD domain (100k user, or for example less users
and more jpegPhoto) is too close to comfort to the 4GB limit of TDB.  

There are probably very good reasons to seriously evaluate it anyway,
but it just seems a pity we didn't get over the 64bit hump with our own
