Right now, there is no boundary structure, so it runs in quadratic time.

Finally fixed in r25!

Interestingly, implementing the approximate linear algorithm (by only scanning 
triangles incident to vertices in the cache) as opposed to the "exact" (as 
exact as a heuristic might be) quadratic algorithm results in smaller files 
with better cache hit ratios.
