I don't understand your problem here.  If you're ptrace'ing a process,

I have a root-process that spawns threads that I want to monitor. To be able
to ptrace() all its threads (and the threads descendant threads/processes)
in the way you suggest, I need another process to monitor the root-process.
That I can't do, I just want to monitor the treads and follow
forks/exec/create_thread etc. It's a pity that ptrace() needs a parent
process to monitor a child, and it can't trace itself from within a
thread/process.

Cheers,
