You mean like while an application is running? Wouldn't that break a lot of 
applications, which store filenames in memory during runtime? 

In the current implementation, for every shitemid that is constructed, all 
drives are queried and their paths are canonicalized, which is a lot of disk 
i/o and string copying. Unixfs is really painfully slow. I guess we need some 
caching scheme, but if you don't like the current one, I'll give it some more
