	While not tested with Excel, I /have/ encountered cases where an
application has locked the file for writing, but multiple readers are
permitted. Those would fail then if one attempts to write. {The other view
point is a library that does a complete open/read\write-all/close to memory
-- such an application might open/read/close, then Excel opens/locks, with
the application only learning of the change when it attempts the
open/write/close cycle}
