Thanks Andrew!

First, Job can work as a standalone kernel module.
The current implementation provides the inescapable job container.
Job provides global unique Job ID (jid) to processes in a cluster
environment. Job initiation on Linux is performed via a PAM session
module with authentication and security checks. Root level processes,
or those with the CAP_SYS_RESOURCE capability, can create new jobs
or escape from a job.

Second, Job based batch schedulers or resource limit tools can take the
advantage of the process control ability Job provides.

Thrid, Job provides a registion mechanism to various accounting modules
for setting and getting job based accounting information.
CSA (Comprehensive System Accounting) is one example of the accounting
modules, (CSA code maintainer Jay Lan is currently on vacation, he will
be back at Feb. 1).

We are pushing Job to linux kernel. If anybody has been using Job in your
open source software, please respond to show the desirability and
interest-level for Job, and we highly appreciate your suggestion on its 
completeness as well.

Thank you!
