Well, I wrote a quick and dirty /proc ps some time in the past. The
motivation was that regular ps gets stuck when an I/O device is not
available, but the /proc based ps doesn't, hence it will allow you to
see all the processes, whether one is stuck on I/O or not. It's also
a lot faster than regular ps. Right now it only does
process_id terminal user process_name
But it would be trivial to add more functionality to it if desired.
Disadvantages: must be suid root to be useful for a normal user. (since
currently it has no flags and uses no temp files, there is very little
that could be exploited as a security hole.) In fact the entire file
is 68 lines long.
