Are you certain that is a general behavior?

For example, I have Preview open right now, and it very much lists all
its open files:

iodine:~ shultzc$ lsof -p 1379 | grep pdf
Preview 1379 shultzc  txt      REG       14,2    189325 9688581
/Users/shultzc/Downloads/758206463.pdf
Preview 1379 shultzc  txt      REG       14,2     91087 9682563
/Users/shultzc/Downloads/jo001518o.pdf
Preview 1379 shultzc  txt      REG       14,2    492849 9684998
/Users/shultzc/Downloads/pat5925487.pdf
Preview 1379 shultzc  txt      REG       14,2    818740 9682461
/Users/shultzc/Downloads/103_34.pdf

Ditto for Pages:

iodine:~ shultzc$ lsof -p 13384 | grep pages
Pages   13384 shultzc   13r     REG       14,2     93930 7814760
/Users/shultzc/develop/Synthetiq/forms/2010-09-14_Apple_fax.pages

I _do_ see that OmniFocus uses a cache instead of the underlying
database (kudos!), but unfortunately I don't actually have Office, so I
can't test the OP's scenario.

But it does seem from the above that this can be handled in an
implementation-specific manner, no?  (Please forgive my ignorance, I
develop mostly with iOS.)
