Subject: key-data.c (key_struct{set,steal}): Assert no other references.
X-Git-Url: https://git.distorted.org.uk/u/mdw/catacomb/commitdiff_plain/a6864ad907239985bd1f6eab414cec6171930d46

key-data.c (key_struct{set,steal}): Assert no other references.

Otherwise I predict serious trouble when someone gets the reference
counting wrong.
