- Defines value is `1024`.
- Specifies number of `RBasic` per each heap page.
+- To calculate the number of bytes per heap page, it is "(size of management data per heap page) + (size per object) * `MRB_HEAP_PAGE_SIZE`".
+ In mruby 3.1.0, the "size of management data per heap page" is 6 words, also "size per object" is 6 words.
+ For a 32-bit CPU, `(6 * 4) + (6 * 4) * MRB_HEAP_PAGE_SIZE` gives the bytes of size per heap page.
+ Conversely, for example, to keep the size per heap page to 4 Ki bytes,
+ calculate `(4096 - (6 * 4)) / (6 * 4)` to specify `MRB_HEAP_PAGE_SIZE=169`.
