locking code in the ldb_tdb backend, except for a single read lock during searches to ensure searches don't cross transaction boundaries The tdb transactions code would map these extra locks to noops anyway (as locking makes no sense inside a transaction), but the work in setting up the locking keys still costs something, and it makes the code needlessly complex (This used to be commit 1b8d368a6771360fb0626127c02b3eb95f3eae59)
