I finally looked at the kernel changes.  They look fine to me, and are
reasonably simple.  But someone more familiar either with the ptrace
or LWP machinery probably ought to look.  Maybe you should ask
core%netbsd.org@localhost?

You say you did the debugger side of this for GDB 7.0.  GDB 7 is GPLv3,
isn't it?  Is there any chance you could implement thread support for
the older version of GDB currently in the NetBSD tree?
