Any number of processes can hold SHARED locks at the same time, hence there can be many simultaneous readers. But no other thread or process is allowed to write to the database file while one or more SHARED locks are active.
A file lock is used to serialize write access. W hen reading the file is not locked. This makes little sense. There are no 'shared' locks.
