Introduce a new execobject.flag (EXEC_OBJECT_CAPTURE) that userspace may

Use this at your discretion, the contents of the error state. although
compressed, are allocated with GFP_ATOMIC (i.e. limited) and kept for all
eternity (until the error state is destroyed).

Thanks Chris.
I would love to give this patch a try, but I can't figure out what it
applies to. It looks like it applies on top of another of your series
-- I looked in your linux-2.6 repo, but didn't spot the appropriate
branch.
Did this get anywhere? Do we have an easy way to decompress the instructions, or
should we just use the debug flag to disable compression?
