A simple attribute lookups shouldn't be *that* expensive either. It would 
basically be one additional syscall per file and the concerned block would 
very likely be already cached, since Tracker reads a lot more info for the 
files anyway. Unless those thousands of file names actually need to be 
translated, the additional overhead is probably not even measurable. 
Doesn't harm to actually test this, though.
