On SYS_ALLOC we will add a new FixedWidthAllocator if the old ones
are already full or we don't have one with proper size. This allows
arbitary number of allocations as long as you have enough memory
available :)
Next I will be writing a general allocator for allocations larger
than 4096 bytes which should make SYS_ALLOC syscall complete :)
