PLEASE don't go around publishing internal addresses like this requests,
since such addresses are GUARANTEED to change and BREAK programs which
count on them.  Some parts of an operating system are hidden from
view ON PURPOSE, so the OS can be sure that its data structures will
not be fooled with by user programs.

The correct procedure in this kind of situation is to say, "Gee, Atari,
I lose memory over time.. I wonder if there's a problem in the memory
allocator?  Here is an example program which demonstrates the problem..."
I know we won't always have a fix for the problem by next week, but
f**king around with GEMDOS' internal structures will cause more trouble
than it's worth.

*** FLAME OFF ***

As it happens, we know that memory gets fragmented strangely, and the
limit on memory blocks you can Malloc is a function of statically-allocated
data structures.  In future ROMs, we may increase the limit, but we
can't get rid of it without a new, more fragile memory allocator (one which
assumes that you haven't changed memory locations immediately before and
after blocks you allocated).
