Yes - you are correct :-)

It looks like FB server (super on my MDK box) does not keep an open
handle to the db file for any noticable time.

However if you were to replace the database at the time a transaction
was being commited (when the server has an open handle) then a window
for this scenario could exist and the committed transaction would
'dissapear'.
