This is actually about genalloc. The genalloc documentation is high
level and mostly about the API, while this talks about the guts of the

belong to the generic genalloc documentation.
I will move it to the .c file, but isn't it too much text in a source file?

I'll put "size in bytes of a chunk of memory"

ok, also for further occurrences
