Clearly if you want a chain of N payloads, then you are going to need
to have N-1 payloads that cleanly return.  Thats just going to have to
be one of those assumptions that we can't change.

I would prefer to keep each payload as standalone as possible - they
shouldn't have to know they are being managed by the chooser.  So, yes,
if the payload errors out and you want bayou to know about it, then 
you'll have to make sure it returns an error code of some sort. 
Again, this is reasonable, and easily managed with libpayload.
