not sure about the Python bindings off hand; general approach for
other systems if /proc (not just /proc/stat) insufficient consists of
one or more:

direct kernel data structure interpretation - also fast, but also very
arch. specific. you could perhaps use lsof or top or other interface
to cross-platform vars of this sort where /dev/kmem or /dev/mem is
present.

kernel audit or profiling facilities like performance counters,
kprobes, security hooks, other common facilities.

this will cover all common platforms but is more time consuming and
maintenance intensive than would be ideal...

good luck,
