Finding if a process is active

[Guy Harris]

>I thought that the "name" was stored in two separate places?

It is, but that's not a "name" in the sense that it uniquely identifies
the process.  It's just the first N characters of the last component of
the pathname of the last program "exec"ed within that process.

I.e., there are *lots* of processes "named" "sh" or "csh" on most
machines....
