* Correct calculation of CPU time. * Fix a bug on newer versions of FreeBSD where computing the process map leads to a tight error loop. * Add support for the new procstat API to obtain the list of open files and cwd. * Use kvm_openfiles instead of kvm_open to better handle error messages. * Split some modules out into non-suid modules. * Properly determine the number of CPUs. https://bugzilla.gnome.org/show_bug.cgi?id=605431
