I've tried to go through and clean up most of the b) issues, although
some have apparently slipped by. Please let me know of any others you
ran across.

And indeed we've hit a few of issue a) already, so I should probably run
through and do a full audit.

Your patches look fine to me. Do you intend to push them or should I
queue them up?
