How do you deal with the fact that $continuation changes very
frequently?  Here's (in my ind) the obvious way to approach this: The
GC is tracing some old value of $continuation.  When it's finished,
there's a new one there, with new frames hanging off it.  So the
tracer needs to go back to the new value.  Is there a guarantee this
process will finish if the steps have bounded size?
