utils: helper function to print top memory allocation site
The memorytop function uses Python's tracemalloc module to show the
source lines / backtraces with the largest remaining allocations. This
allows identifying the origins of active memory by placing calls in
strategic locations. Allocations from C extensions will show up as long
as they are using the Python allocators.
