complexity wise your approach is the best one of all that I have seen till
now

this is obviously memory efficient but I don't know whether this approach
would be faster than previous approaches, with previous approaches there is
no call back into Python code from C code for comparison.
but this should be faster than HeapDict as HeapDict is directly using its
own methods for heappush, heappop etc
