+- tdb2 provides tdb_deq() for comparing two struct tdb_data.
+
+- tdb2's tdb_name() returns a copy of the name even for TDB_INTERNAL dbs.
+
+- tdb2 does not need tdb_reopen() or tdb_reopen_all(). If you call
+ fork() after during certain operations the child should close the
+ tdb, or complete the operations before continuing to use the tdb:
+
+ tdb_transaction_start(): child must tdb_transaction_cancel()
+ tdb_lockall(): child must call tdb_unlockall()
+ tdb_lockall_read(): child must call tdb_unlockall_read()
+ tdb_chainlock(): child must call tdb_chainunlock()
+ tdb_parse() callback: child must return from tdb_parse()
