I'm not well-placed to say.  I try to let the code act as its own
commentary as much as possible.  Here, I think that a person who knows
the code base knows that if the function exits because a property's
calculation is in progress, it is to avoid triggering that calculation.
However, if anyone feels that this is not pick-upable upon reading,
please add the comment!
