Cool, you found it. CODA_STATFS is actually a relatively recent
addition. it used to always return fake information and not make
an upcall at all. Now it gets local cache size and usage from venus.

Hmm, I should look at the source again, why 'coda_nb_statfs'... would
the 'nb' stand for 'non-blocking?' Basically if we return the fake
information it will work exactly like it used to.

I'm not sure how easy it is to tell if we're already mounted or not.
