--- Comment #1 from Mike Kaganski <mikekaganski at hotmail.com> ---
So a guess would be that when opening it read-only on Windows, LibreOffice
doesn't use correct mode (read-only, shared) - see CreateFile's dwDesiredAccess
and dwShareMode [1]. Note that from Windows share PoV, the file is not open
from Linux side, it was atomically opened when read, then was closed, than will
be attempted to open for writing later (IIUC the mechanics of Linux file
operations). LO only detects the opened state using lock file.
