How about a second list made up of thread_info structs for lwps?  That way, the current
thread routines wouldn't have to constantly validate whether the list item was
a thread or lwp.  This also would simplify the numbering system.  There
could be equivalent lwp routines for accessing the list (e.g. iterate_over_lwps() ).
