Just out of curiosity - is there some kind of writeback strategy
employed in ldb if the variables are stored in memory ?

I had this question from the idea that performance issues can be
pretty much be dealt with if part / entire dbs are shifted into memory
with periodic writeback. This should sound more like caching in
implementation.

The decision to make a variable / parameter memory based+writeback,
can be configurable parameter again :)
