Yeah, thinking more about this, this can't work. I think you'd need to
use "/proc/<tgid>/task/<tid>" wouldn't you?

Or perhaps even more complicated, and say "if it's a task group
leader, keep the old /proc/<tgid>, otherwise do the full thread path".

Anyway, does not not sound worth it. Your previous simple patch is
probably the right thing to do.
