Ok, I can reproduce:

$ rm -r __pycache__/; ./python repro2.py 
ready
<module 'anon_city_hoods' from '/home/antoine/cpython/opt/anon_city_hoods.py'>
1047656
VmHWM:	 1047656 kB
VmRSS:	   50660 kB

$ ./python repro2.py 
ready
<module 'anon_city_hoods' from '/home/antoine/cpython/opt/anon_city_hoods.py'>
77480
VmHWM:	   77480 kB
VmRSS:	   15664 kB


My guess is that memory fragmentation prevents the RSS mark to drop any further, though one cannot rule out the possibility of an actual memory leak.
