Eric Blake d1dde7149e bitmap: Update count after a merge ... We need an accurate count of the number of bits set in a bitmap after a merge. In particular, since the merge operation short-circuits a merge from an empty source, if you have bitmaps A, B, and C where B started empty, then merge C into B, and B into A, an inaccurate count meant that A did not get the contents of C. In the worst case, we may falsely regard the bitmap as empty when it has had new writes merged into it.
