procps upstream looks to be no longer active. The last change to the CVS repository seems to be 3 years old and the mailing list archive is mostly just full of spam. It looks like Arch Linux, Debian, Fedora and openSUSE have moved on to procps-ng. I suggest we do the same during the v1.8 development cycle if possible. procps-ng is actively developed and looks to be open to patches.
