Sure, but still, doing a million nested function calls (and god knows what
hides behind the particular fwrite() implementation) (and a vertex count of
one million might even be realistic for physics models) doesn't really sound
that fast -- especially as a cache is meant for speeding up things, its
implementation should probably be optimal :)

Not to speak about the fread() loop ...
