   1. In parallel (via [rayon](https://docs.rs/rayon)) serialize and compress each dirty leaf with zstd (configurable via `Config.zstd_compression_level`).
   1. Based on the size of the bytes for each object, choose the smallest heap file slot that can hold the full set of bytes. This is an on-disk slab allocator.
-  1. Slab slots are not power-of-two sized, but tend to increase in size by around 20% from one to the next, resulting in far lower fragentation than typical page-oriented heaps with either constant-size or power-of-two sized leaves.

   1. Write the object to the allocated slot from the rayon threadpool.
   1. After all writes, fsync the heap files that were written to.
