 # Mempool
 
-A memory pool implementation.
+A memory pool of fixed-sized blocks with O(1) allocation and deallocation.
 
 Each block in the pool is tagged with a boolean value that indicates whether the
-block is free or in use. The allocator otherwise maintains little additional
-information. Therefore, some operations have linear-time complexity.
-Specifically:
+block is free or in use, as well as a pointer to the next free/used block.
+Blocks thus form two lists, a free list and a used list. The allocator
+maintains the two lists when allocating/deallocating blocks.
 
-- Allocating a block scans the pool for the next free block in linear time.
-- Freeing a block runs in constant time.
-- Iterating over the pool's used blocks is linear over the number of blocks in
-  the pool, as opposed to just the number of used blocks.
+The allocator's internal data is stored separately from the block data so that
+the data remains tightly packed.
 
-The allocator's internal data is also stored separately from the main array of
-blocks so that the block data remains tightly packed.
-
-For convenience of programming and debugging, free blocks in the mempool always
-remain zeroed out. If your data structures are valid when zeroed out, then you
-do not need to explicitly initialize them.
+Free blocks in the mempool always remain zeroed out for convenience of
+programming and debugging. If the application's data structures are valid when
+zeroed out, then they do not need to be explicitly initialized.
