I don't understand how ReallocMem could ever work under AmigaDOS unless the
caller always does a Forbid before the FreeMem and a Permit after the
ReallocMem.  As soon as you free memory on the Amiga, some other task may get
a chance to run and get the block you just freed.  (Memory blocks are either
in use, or completely free - available to anyone.  There are no other
possiblilities.)  With Unix, each process gets its own private virtual address
space so that the other guy's alloc won't interfere with your alloc.  And sbrk
provides contiguous blocks of virtual memory, something which cannot be done
with AmigaDOS.

You keep saying that it is trivial to add ReallocMem to the OS.  Given the
fact that all tasks on the Amiga share the same virtual=physical address
space (currently), I believe it is very difficult.  I would venture to say
that it is impossible in version 1.x - you will have to wait for 2.0 or 3.0.
