This depends on the thread model used. If I am running under the old
linux threads (non NPTL), each thread is a process, and both stat
and tasks report the wrong information.

Same...

>/proc/<pid>/task in NetBSD?

Our linux emulation needs a lot of tender love and attention so that
it will be able to emulate applications that assume and require NPTL.
We could in the short term fix procfs to create the task subdirectory
and populate it with the information from curproc, but I don't think
that this will be enough.
