I would be very surprised if the finder implemented the locking protocol
necessary to insure simultaneous update access to the desktop database.
Your best bet would be to see what appleEvents the Finder accepts, (documented
in Inside Mac Vol 6) and if there are not appleEvents to get and put the
finder info, petitioning Apple to add them pronto. Inside Mac Vol 6 may be
available from APDA, and all registered developers got a copy on the Big Bang
and Beta Bang System 7 CD-ROMs.

If you just write into the file while the Finder has it open, you will
make the structure the Finder has cached about the file into garbage, and
it will garbage the file the next time it writes.
