Collective resource limits - final status report

[Gabor Kovesdan]

The code has been merged to Edward's hrl and containers work and now 
uses containers to usage accounting. The kernel-level support is ready 
for basic system calls to deal with jobs and JLIMIT_NUMPROC is 
completely ready. Other resource limits have the code to count the usage 
through containers but actual usage enforcement is not complete. The 
test suite has support for creating a job, adding processes by forking, 
starting a shell imprisoned to a job and setting various resource limits 
but resource consumption is mostly incomplete. The userland support also 
need to be done.

So my current TODO list is the following:
- Complete limit enforcement for all limits
- Complete test suite with resource consumption, so that the limit 
enforcement can be tested thoroughly
- Add userland support for various databases so that it can be used just 
like in IRIX. Also add support to various utilities, like ps to list 
processes inside a specific job.

Soon, I'm leaving to Portugal for a one-year intership and this will 
take some preparations and then I'll have to settle down there but once 
it's done (around Sep 20-25 as I expect) I'll continue working on this 
project.
