Hi All,
'ptrace' is documented as acting on processes: it takes a PID as an argument.
So if we are in a thread environment, where do we get registers for a
particular thread?
What does the user area mean in a threads environment?
How is this different between NPTL and Linux threads?

PID on GNU/Linux in this case is what other operating systems call TID.
It's a kernel process ID and each thread is a kernel process.

Not at all.
