correct, except in this situation, if exim was writing to the file
precisely when the routine deleted it, presumably the new exim
creation would merely be non-existent and lost.

no, each server runs it's own exim, and all deliveries are to locally
mounted drives. Not NFS.

Perhaps, but then with multiple deliveries it would be my own pipe
mechanism which would have to observe locking, as each message would
need to be run sequentially. More complicated than letting the present
set up. Altho when a race happens, everything gets complicated anyways.
