I can also confirm that the patch appears to work correctly on Mac OS
X. I tested with this patch and with the "quick distance calculation
v1" patch also applied.

On a 2 GB, 2 GHz Intel Core 2 duo machine, a combined map of France,
Germany, Switzerland, and Italy took about 45 minutes to compile.
Without these patches, it took about 1 hour and 40 minutes.

Sorry, I didn't test the patches separately, so I don't have data on
the individual performance improvements.

At any rate, with superficial testing, both patches seem to be stable. Thanks!

Cheers.
