16 Notes:  Process directory segments are temporary segments associated
17 with each interactive, absentee, and daemon process.  For system
18 efficiency, it is desirable that as many volumes as possible be
19 available for process directory segments.  However, a volume cannot be
20 dismounted while it is a pdir_volume, or while process directory
21 segments reside on it.
