I should also note that for bash the primary bug and discussion venue is with email to the bug-bash AT mailing list.  That is the better place to discuss bugs.

Also since you are asking for help the better venue is the help-bash AT mailing list.  That's the best place to ask questions such as this.

You have reported a bash issue against the Savannah Administration project.  We don't have anything to do with individual projects hosted at Savannah.  I will transfer your ticket to the bash project.

However separate from that I suggest you look at the setsid(1) command which runs programs in a new session as that appears to be what you are wanting to do.

I was battling this problem now for several hours

i wanted to do this:

{ a | b; } & pid=$!

and then later

kill -- -$pid

to kill all the processes spawned by the pipeline.

But this proved to be immensely complicated as no new process group is spawned from within a script (unless set -m which is not recommended)

Please, provide a syntactic construct to spawn a new process group (or at least there should be some usable command to do that).
