- Removed reference to RH9 and LinuxThreads from INSTALL.LINUX

- Fixed a bug in the always activation mode which would cause a segfault on
    shutdown.
- Removed the Linux work-around for killing proceses (with killpg).
- Processes forked by the activator now have their own process group to
    ensure they don't receive keyboards signals (SIGINT, SIGQUIT) from the
    node.
