Since Runewalsh is deep in it, clearly we're not off worse if we change it :-)

So, in order to progress: we'll throw it in the wild to be field-tested.

So I propose the following: I will add the new heap manager in a new file.

I'll include the old and the new one with an IFDEF, activated by default so it will be tested. 
In case of trouble the old one can be reactivated quickly using a simple recompile of the RTL.

If after 3(4,5,6) months we don't get bugreports, we remove the old one
unless Runewalsh fixes the bugs.

Unless there are objections, I'll implement it this weekend.

Michael.
