It actually ends up being the same, and bit more generic to go with
lowest, because target_attach should always adds the main thread first.
Otherwise, there's no such concept of "main" thread in the common code.
"The thread with pid == lwpid" holds true for NTPL/Linux, but not everywhere,
and even then the leader thread may have exited already.  I'll update
the comment.

Thanks,
