Sorry, that didn't mean that I wasn't interested in other people's
opinion. It's just that I explicitely addressed the people that would
probably implement such a change.

Hm, is that unchangeable?
My intention was the following: I have spent some thoughts on taking over
an ELF implementation (for shared library support) for MiNT. All of the
existing implementations I've seen are based on a page size of 4k. I
am sure that this could be changed to 8k for MiNT but I don't know how
much extra work this would cause when porting such software. Anyway, the
page size will only become relevant when MiNT provides a virtual memory
management.
So, all of you: Should I change the chunksize to 8k in malloc() then? As
I've mentioned before, I am not familiar with the internals of malloc and
so I can't say if such a change would have negative side effects.
Ciao
