start looking into memory handling

+ Now 10M alloc/frees succeed, which totals more memory than the virtual
  machine has, so no too obvious leaks are occuring. For future
  debugging speed, changed 10M to 1M.

+ Also quick fix to rpcs, stacks are now assigned. Not entirely sure why
  they worked before this, but good that I found it.
