[Info-vax] Orphaned processes on OpenVMS

[Wendell]

One of my biggest aggravations with *nix is the persistence of
orphaned processes. Say an app hangs. I log in to another virtual
terminal and "kill" it. That leaves various, no longer needed
processes still running, and the only way to really clean up is reboot
the system. At the worst, these stragglers can interfere with
restarting the app I had to kill.

I've heard it said that OpenVMS doesn't have this problem at all. How
does it prevent orphans or at least allow cleanup without rebooting?
