What open calls are done entirely depends on client
behaviour. This is something we don't have under control at
all and varies a lot based on client OS version, installed
software on the client and a lot of other things. I've seen
virus scanners on the client doing very weird things here.
You can't depend on a file being opened only once.

Sorry, without knowing *why* you need to do this I believe
we can close this thread here.
