Yeah, I was mostly thinking that it would be good to check for other missing includes while touching the file, so that it doesn't have to be touched again later if there is a missing stdlib include or so.

💬 martinus commented on pull request "Add pool based memory resource":
(https://github.com/bitcoin/bitcoin/pull/25325#discussion_r1125443783)
In line 89 there is an assert that `ELEM_ALIGN_BYTES` is multiple of 2:
```cpp
static_assert((ELEM_ALIGN_BYTES & (ELEM_ALIGN_BYTES - 1)) == 0, "ELEM_ALIGN_BYTES must be a power of two");
```
So given that line 91 should make sense, `ELEM_ALIGN_BYTES - 1` becomes a bitmask and actually asserts that `MAX_BLOCK_SIZE_BYTES` is multiple of `ELEM_ALIGN_BYTES`. But right, on its own that assert wouldn't be enough and using `%` is probably a bit more clear.

Posting here now, I can add this as a comment later:
The value here determines the maximum bytes that the `PoolAllocator` supports. When bigger blocks are allocated, this is just forwarded to `new`.
The thing with `sizeof(void*) * 4` is, it is not enough to just support up to sizes of the `std::pair`, because the different implementations of `std::unordered_map` use more memory for each node. Most implementations wrap the std::pair into a struct that contains a single pointer, so they can
