Hooray, they've finally got a partitioned lock manager. The lock subsystem has 
always been a huge bottleneck in previous releases...

The last time I looked at 4.7, the main problem was that they stopped 
exporting the __lock_getlocker() function. As a quick hack to allow testing 
the rest of OpenLDAP, I just patched it back in to my copy.

The clean approach would be to once again resurrect the long-lived 
read-transaction code that we dropped a long time back.
