Hi Val,

What does randomly mean in this context?
If one entry is removed, does Ignite reuse the space for new entries with
the same or smaller size?
Does Ignite organize it in small blocks? If yes, what happens if all
entries stored in a block were removed?
What does happen in case of a cache-clear?
