With the default VFS for QNX - "unix" the WAL did not worked, using "unix-excl" worked fine. All the connections are used within the same process (one connection per thread), the data structures used to synchronize the readers/writers will be placed in heap, instead of shared-memory. It should be better also for performance. Of course the database file will be locked, and cannot be used by other process. Maybe the WAL documentation should be extended with a note for QNX.
