note: it may seem as though blink / webkit coding style is to leave all
parameters unnamed, but actually you should give this one a name. the style rule
is to leave parameters unnamed when the best name for the parameter is the type
name. in this case, the name of the parameter is probably "name" or "frameName".

 
     // This frame set its opener to null, disowning it.
