SharedUnixLibrary and the System Heap

We are looking at some tightening up of the memory protection in RISC OS 
  and one of the possibilities is to protect the system heap against 
user  mode accesses.

Unfortunately SUL does this, so protecting the heap would break a lot of 
things.

Switching to a privledged mode within SUL in order to access the heap 
seems like a sensible solution.

Does anyone see a problem with this? Or have a better solution? etc.

Thanks,

Matt
