Trace python statement execution and syscalls invoked during that simultaneously

Shows space used by each directory of the root filesystem excluding mountpoints/external filesystems (and sort the output)
Excludes other mountpoints with acavagni's "mountpoint" idea, but with -exec instead of piping to an xargs subshell. Then, calling "du" only once with -exec's "+" option. The first "\! -exec" acts as a test so only those who match are passed to the second "-exec" for du.
