If you don't mind having your Web-Server with 1000 connections/second be a "single user", just scan for all the unique UID/GID pairs. All the root processes are one "user", the lpd is another user, Apache is another user, login-joe is another user, etc. The total number of tasks is the number of directories that represent digits in /proc.

I was going to compile a list of innovations that could be attributed to Microsoft. Once I realized that Ctrl-Alt-Del was handled in the BIOS, I found that there aren't any.
