(From update of attachment 32410)
I'll have to check into whether this works - I don't remember whether there are
special alignment or lazy commit requirements.

But I also noticed that PLATFORM(SYMBIAN) uses fastMalloc in place of VM
allocation inside Collector.cpp. That's definitely bugus - the GC counts on the
guaranteed alignment provided by vm_map, VirtualAlloc and posix_memalign.
Failing to meet the alignment requirements will lead to random crashes. If
Symbian has no way to get aligned memory chunks, it needs to do a trick to fix
up the alignment, like the mmap() code path.
