I knew this, but I never realized one of the implications before: If 
you're working on writing macro code, and you start a render, you may 
break the render by editing the file the macro is in before the render 
is done, yes?

(Of course, on decent operating systems, and even Windows, reading the 
same file a bunch of times in a row isn't all that much overhead, 
compared to reading it the first time.)
