	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 ...
