But if you eventually F/free() the other two, the three chunks of memory
(in the above example) will be coalesced by the o/s, won't they?  (Assuming
no intervening allocations that haven't been free'd.)  In other words,
if I run multiple processes, each doing any number of memory allocs in any
order, providing they all properly free the memory before terminating,
AmigaDOS will coalesce all of the adjacent free'd spaces won't it?  May
sound like a stupid question, but the way Peter phrased his answer, I had
to ask.  [I'd RTFM, but it hasn't been published/released yet :-)]

Every time I see this .sig line, I think of the poor souls that think
Windows (tm) is representative of what the rest of us mean by multi-tasking.
