Oh, no need to do that for every function.  It's just customary to use
function comment when there's sufficient amount to explain for the
whole function.

Hmmm... maybe I was too ambiguous.  Because the behavior is quite
unusual and can make the error handling behavior deviate, I think it
deserves to explain 1. why such behavior is necessary and 2. what the
implications are (e.g. in corner cases, how long it could add to reset
timeout) and preferably 3. rationale for choosing this specific
approach given #1 and #2, so that when someone else reads the code
later on [s]he doesn't have to second-guess the original intention of
the workaround.

Thanks.
