Abstract
After the mark phase, all objects have been identified as reachable or not. Those reachable are being marked by a dedicated bit. Some of the marked objects may be additionally marked as pinned by another bit. At this moment Garbage Collector has all necessary information to start its job. But the question arises - should it proceed with Sweep or Compact collection?

Notes

The only exception could be the first plug not preceded by any gap, but we can omit it in our considerations. And as we will see soon, in fact each generation begins with a single empty object so even the first plug is always preceded with a gap.

Although there is no real gap here, GC needs to account it for its statistical purposes.
