You can easily achieve it by changing gtags/gtags.c file especially in
incremental() function.
But it might be worthless. Though scanning tree seems to be redundant,
it does not so take time. It is updating database to spend a lot of time.

BSD Db library is not suitable for this usage. It is being examined to be
going to replace the database system with another one in the future.
