  I have repeatedly grappled with the question of how the convective Urca
process affects stellar evolution, in particular during the high-density
convective carbon burning that can occur in near-Chandrasekhar-mass white
dwarfs. This manuscript collects some fragmentary thoughts from various failed
and abandoned attempts. This is not a complete work, does not provide a
comprehensive overview of the literature, and has no definitive conclusions. It
is posted in the hope that some part of it might prove useful to someone at
some point in the future. I also take this opportunity to include anotter
important result of more general interest (Appendix B).
