There's something of a missed opportunity there, as a correctly programmed
mmap() / MMU handler can do wonders for avoiding heap fragmentation - you can
map several non-contiguous physical addresses to contiguous virtual
addresses, providing application layer code with what looks like a single
large block of memory.
Laters,
