But what you are really asking is how close this is to the optimal.
I didn't include that in Patch 5 details, but I was able to look at
my notes and see that the sparse_path_count data point was 1,962,
meaning there are that many sparse trees in the sparse index before
expanding. Thus, the 6,521 lstat() calls are 3.3x more than the
absolute minimum required.

Nice, and still impressive.  Thanks.
