Also comments by several others..
Ok so here's how it looks to me now: (still not final)
#1 struct proc (decided)
#2 struct schedgrp ,lpwg (lwp-group), prigrp (priority-group)
subproc (subprocess)
#3 struct upctx (upcall-context), virtcpu, thrdslot (thread slot)
#4 struct lwp (decided)
usually the 'lwp' will be passed around so diffs to NetBSD will be minimalised.
my favourites are:
proc, subproc, lwcpu, lwp
lwps are parcelled out to lwcpus to run when the appropriate subproc is
scheduled.
