I've tested threaded one and INTERRUPT immediate re-triggering and at
least the apparent cases work fine.  I've re-generated the git tree on
top of 3.0-rc1 with the updated patches.

 git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git review-ptrace-seize

The commit ID should be 7eae14288e745cfaabeb035fa67f89eb63a1aff7.  As
git.korg seems to be taking quite a while to sync, it might be a
better idea to pull from master.korg.

 ssh://master.kernel.org/pub/scm/linux/kernel/git/tj/misc.git review-ptrace-seize

IIRC, pending issues are...

* Which signo to use in exit_code on STOP traps.

* Implicit signal on clone.

* What to do about events which are reported by genuine SIGTRAP
  generation?

* Group leader exit issue.

Thanks.
