Please note while iterating through, you can NOT modify records in place
because they can be moved and this can screw you up. This is how it
works for NextModifiedRecord any how (this fact is a one liner somewhere
in
http://www.palmos.com/dev/tech/docs/conduits/win/ConduitCompanionTOC.html.
The 0.9.5 (well, pre code still i guess) sync.c code handles this. In
fact, you may want to use this since it implements all the sync logic as
defined by palm.
