[Oberon] SystemV- Heap + Module Space

Joerg, Andreas,

I see, thank you for explaining. Is just part of my exploring &
learning. 

Re Type descriptors kept in mem. Running GC, just after unloading and
before next loading, will it increase this quazzy safety?  

I am sensible as far as unloading modules from the inner core.

But I admit, I tried unloading EDIT module, that at first sight
appears save to free, when there is no file opened in a user viewer so
perhaps nothing is referenced. But proved the opposite.

Many thanks.
