I didn't intend to close this PR -- looks like something weird happened. |

If you're compiling with g++, compile with address sanitizer ( -fsanitize=address and link against libasan), e.g. for examples/surface.cpp g++ -g -Wall -fsanitize=address -o surface This will show you all memory leaks. Before your changes, and after. |

In a program I wrote, I had to plot a few hundreds of matplotlib plots, and memory usage went up to 5 Gb despite calling
plt::clf()andplt::close()after each plot. Removing all instances ofPy_INCREFseems to solve the issue, sincePy_INCREFis not needed on return values ofPyObject_GetAttrStringandPyObject_Call, according to https://docs.python.org/3/extending/extending.html#ownership-rules.
