These patches make the code worse.  If we're in the middle of a loop,
then we should clean up the partial loop before doing the goto.
Otherwise it creates a mess when we add a new allocation function after
the end of the loop.

Someone is going to add a _scoped() loop which uses cleanup.h magic to
call _put automatically.  This is a good option.
