Yeah, uClibc does that.  It's not as bad as it seems because both the dentry 
and the page stay in cache.  (The uClibc TZ is a tiny text file, one line, 
generally about 6 characters long.)

Having the libc cache the data isn't really much of an improvement over having 
the kernel cache it, but if this is enough of a hot path you might wanna poke 
the uClibc guys...
