Hello,

BTW, I'm pretty close to send the second take and the INTERRUPT trap
has changed quite a bit.  It got renamed to PTRACE_EVENT_STOP and now
acts as both group stop trap and INTERRUPT trap.  IOW,
PTRACE_INTERRUPT makes tracee go park at group stop trap site.  The
whole thing is much prettier this way.  Well, being ptrace, it's not
really pretty but at least it is much less disgusting.

Thanks.
