IMHO these "view" extra stats really hurt. Think about high latency accesses 
to the filesystem (e.g. nfs) and about the fact that today the startup times 
are still rather bad on the linux platform.

On the other hand your concern is real and a daemon taking care about an 
uptodate cache is much more efficient. In addition if done correctly the 
applications can simply mmap the db read-only into their memory space.

Last but not least the daemon shall provide a run-once option for systems with 
very low system resources.
