They are place holders for when I can put in a proper assert
function. For now I'm trying to avoid BUG_ON() calls, but
at some point soon I'll replace these comments with calls
to a macro that does BUG_ON() conditioned on a config option
(or something else if there's a better suggestion).
Even though it's commented, the assert() call does what
I want, which is to communicate to the reader a condition
assumed by the code, succinctly.
