will need a separate messaging endpoint per open file. To make this efficient extend the messaging layer to have a new registration function for temporary message types that maps via an idtree. I have updated the LOCAL-MESSAGING test to use the new function. (This used to be commit 4b976851d8b7ccd2c40010be095cef7fecf9e722)
