Do you mean an in-place merge sort using O(1) work space?  If I recall
correctly, That's tricky to program without losing the O(n log n)
worst-case time complexity.

I've not been following the thread, but it seems that a lot of
allocations are being done.  (A high cost was given for freeing the
allocations.)  Merge sort is usually implemented with one scratch copy
of the array, i.e. O(n) extra space.  Which array is considered work
space is flipped as the recursion proceeds.
