Hi Sam,
A very cool idea!

I know of no way aside from hacking the POVRay source to support something like
this directly. But, for what you are trying to do, perhaps the quick thing would
be writing to another file and then replace the one being read with a system
'mv' command or similar. It should be the case that only complete files would be
available to POVRay for read that way.
Regards, Bill
