Because the Amiga has no MMU, etc., we get memory fragmentation
as we allocate/deallocate, right? So, what I'm wondering is this:
If I want to do alot of small allocs/frees, am I going to fragment
memory beyond belief? I'm thinking of something on the order of
alocating a new line buffer every time a line is changed ( including
freeing the old one ). That isn't exactly the use, but it is about
the frequency.
Would it be better to manage my own free pool? I don't like the
concept of pre-allocating large chunks, however.
Does the system unify adjoining blocks of free memory into bigger
blocks?
It seems to me that I _shouldn't_ have to worry about this stuff,
but for some reason I am ...
