Here's a 2.4 version of the signal changes that were accepted into the 2.5
tree for thread groups. It redirects signals to any task in a thread group
to the thread group leader. It then introduces a tkill() system call for
signals directed at a specific task.
This patch does not introduce any behavior changes outside thread groups,
and as far as I know no one is using thread groups in 2.4. It has been in
2.5 for awhile with no problems surfacing.
I'm sending it as a plain text attachment rather than try to fight with my
mailer again. I hope that's acceptable.
