Comment 2 for bug 758164

Actually, the previous comment is inaccurate: I don't reproduce the previous problem of the very first status being slow, but it is definitely slower with uncommitted adds than after commit.

Although the first two status runs are not doing more IO, they are quite noticeably slower, and the difference seems to be mostly in user time
