Dear diary, on Mon, Apr 18, 2005 at 01:29:05AM CEST, I got a letter

No. The collision check is done in the opposite cache - when you want to
write a blob and there is already a file of the same hash in the tree.
So either the blob is already in the database, or you have a collision.
Therefore, the cost is proportional to the size of what stays unchanged.
