Oh, please don't misunderstand. I'm not making any demands or requirements,
what I'm trying to do is to make recommendations based on experience that I
have had with embedding. This sound altogether too much like I'm trying to
push things one way or the other :)
The api as laid out certainly seems to work, and be adequate for the purpose.
I can add here as a point of information that since we
work on windows, there was no need to pass in the "size" argument to the
"munmap" callback. VirtualFree(address, NULL) will release the entire chunk
of memory that was initially allocated at that place. Therefor in our implementation
we can reuse the same allocator structo for those arenas. But I understand
that munmap doesn't have this feature, so passing in the size is prudent.
