rawsock test BUG: soft lockup

Fix
Also there is a re-forking delay added to allow instances to fire up and
back off if resources get low. These changes have been tested with 256,
1024, 4096 and 8192 instances on a 24 thread system with 32GB of memory.

Added an ENOBUFS check on the sender with priority dropping on ENOBUFS
errors and also a timer backoff delay. Added OOM killer respawning that
can be overridden using the --oomable to allow overcommitted systems to
ether respawn OOM'd rawsock instances (default) or not respawn
(--oomable).
Fix
Looks like the kernel is running out of resources and it is doing Out-
of-memory killing of various processes. I think I have ways of reducing
this from occurring.

Hi Colin,
the patch in comment #2 does not work on my system with 128 CPUs. I still got
the BUG: soft lockup, and eventually kill my ssh session.
I think the workaround is making the client (sender) wait for the main process
done with creating all the stressor's instances.
