Hi Anthony.  I wonder if there was a problem when importing my async
command handler patchset.  Since the 'balloon' command completes
immediately, it must call the completion callback before returning.
That call was missing but is added by the patch below.

Needs a Signed-off-by.  I don't recall any fuzz with your patch but that 
was a few hundred patches ago :-)
