Detailed Description

Manages a set of latches, one per store id.

This allows us to grab per-store latches without latching a buffer-pool page, which requires a read, and consumes buffer-pool space.

Used by the btree implementation and by the page allocation.

When a store is destroyed or its volume dismounted, the latch should be removed from the map and destroyed.
