In 3.0.25 we have reworked the idmap subsystem and we made available
both positive and negative cache timeouts for the cache (which is
separate from idmap_tdb itself now).
If you can;t change version you can probably borrow the code from there
somehow. I think I also posted some code for 3.0.24 a few months ago
that implemented a negative caching system with timeout, before we
decided for the major rework.
