Um... on looking closer at profile.py, it's going to need quite an
overhaul to work with stackless -- in particular I think it will need
to keep separate prior frame state around for each tasklet.  I'm not

But I think the lock should be there for when someone gets around to
doing it...  I guess tracing is similar. Maybe something like:
