nit: we prefer staying under 80 char line width if it doesn't make 
the code less readable. Comments should always be under 80 chars.
You can probably drop this comment completely, IDK what value it adds,
the if below is clear enough

ditto

this is also >80 char but more of a judgement call, up to you

Okay, but you're mixing comment styles, above you used /**/
(so does the rest of this file)

This comment block has trailing space chars, please clean up
