 Replying to [comment:3 nickm]:
 > I think this is a good idea.  I'm was confused by moving the remove code
 into circuit_free, but I think it does make sense there.  We should audit
 every caller to circuit_free, of course.

 There are two of those. `429:circuit_close_all_marked` and
 `810:circuit_free_all` and wrapped in FOREACH_SAFE. I'm fairly sure there
 isn't a memory leak there.
