This is easy in a debug build, using sys.getobjects(). In a release build,
you can
use pympler:
start = pympler.muppy.get_size(pympler.muppy.get_objects())
run_complicated_tests()
end =

Benchmarks should measure memory usage too, of course. Sadly that is
not possible in standard cPython.
It's actually very easy in standard CPython, using sys.getsizeof.
Yes, you can query each python object about how big it thinks

Take a look at the benchmark suite at
http://hg.python.org/benchmarks/
The test runner has an -m option that profiles memory usage, you could take
a look at how that is implemented
Yes, out of process monitoring of memory as reported by the OS. We do gather

know this?
